The Tech Talk: Soldering Basics

     Ken Myers shared a soldering video produced by Bruce Simpson of RC Model Reviews.

     He also shared information on his HAKKO FX888D soldering station and how it has improved his soldering technique.

The Business Meeting

     Lynn Morgan, club secretary, noted that we ended the year with 50 paid members, and a total of 57 members. He also noted that the 2018 application is available on our Web site.

     Applications are to be mailed to Lynn (see the header for his address), along with a copy of the 2018 AMA membership card and a check for the dues.

     Membership cards are passed out at the club meetings, or if the member wishes to get the card soon, a self addressed stamped envelop can be sent with the application.

     Members who joined near the end of the year, and whose dues cover 2018 as well, still need to get Lynn a 2018 application and copy of their 2018 AMA membership card.

     Dave Stacer, club treasurer, presented no formal report this month. He noted that the profit from the Mid-Am was up slightly from last year and that the open air swap shape, hosted by Peter Waters, brought in some good money as well. He will give a formal accounting soon.

     For the first time in many years, Rudi Reinhard, swap shop chairman, noted that not all of the table spaces had been sold by our November meeting. He also said that he is still receiving table reservations and expects that we will have a good outcome. He noted that we are hopping for crappy weather on Sunday, as that increases swap shop attendance.

     Ken Myers, club vice-president, told the folks in attendance about the upcoming AMA Update to be held at the Ultimate Soccer Arenas in Pontiac on the evening of Monday, Nov. 20. Details are in this issue.

     Arthur Deane, club president, listed the people who had been nominated for 2018 officer positions.
President Roger Wilfong
Vice-president Ken Myers
Secretary Lynn Morgan
Treasurer Dave Stacer
Safety Officer Bill Brown, Jr.
Board members at large Bill Brown, Sr. and Denny Sumner

     Arthur called for any other nominations. There were none. It was moved, accepted and with a unanimous vote, those nominated were elected.

     After the election, Arthur shared some parting notes.
He said that the flying field in good condition. We worked hard on road to keep in good shape, thanks to the help of Jim Ouillette and his tractor, but that the entrance road will continue to need maintenance.
He was pleased to see the glider group using the field.
He said that the Friends of the Field Fund remains an important factor in our achieving a positive cash flow.
Unfortunately, the membership is on the decline and will continue to do so. For MWRS to survive we might have to consider amalgamation with other local clubs. He reminded us to remember that we have assets so that we should not sell ourselves short in negotiations with other clubs.

     Ken Myers nominated Arthur Deane for life membership in Midwest for his eight great years as president. There was a second. The motion passed.

     Arthur we can't thank you enough for eight great years of service to Midwest. Your leadership and actions were always above and beyond expectations.

     Next month’s meeting is our annual dessert and social gathering. It starts at 7:30 with no aviation video at 7. Bring along something to share in the dessert and snack lines and enjoy a friendly evening of slinging the bull with your friends.

     There will also be a gift exchange of sorts. Bring along a wrapped, useful item that you no longer have use for. You can tag it with your name. We will exchange these items/presents during our social. The idea is not to get rid of 'junk' but to allow someone else to have something that is still useful but that you no longer have a use for.

     The meeting adjourned at a little after 9.

November Show and Tell

the Black Spirit

     President elect, Roger Wilfong, shared his EPP Black Spirit flying wing from Banggood. The kit was very inexpensive at $16.50, shipped. It uses a quad motor and prop, which were also inexpensive. It flies very nicely and is quite easy to keep oriented with its downward facing tiplets. It does needs a lot of lead in the nose area to balance properly.

Confessions of a Soldering Hack
By Ken Myers

     After all of these years, I am still a 'hack' when it comes to soldering.

     This was pointed out very clearly to me when Mike Russell came over and we rebuilt a 3S2P 2500mAh A123 pack into a 6S 2500mAh A123 pack. While we were eventually quite successful, I was embarrassed by my soldering skills, or lack there of, in front of my flying buddy

     Following that visit, I started searching the Internet and YouTube to figure out what I'd been doing wrong all these years. Some of the information I found about soldering was new to me, but other bits of information were things that I'd forgotten about over the decades.

     The photo shows my set of irons in May of 2017. Some have served me well over the years, while others not so much.

     Someone who knows the ins and outs of soldering can immediately see what part of my problem was.

     The uppermost iron in the photo is a Weller 40W with a Charlie White hammerhead tip. It was used to join NiCads and NiMH cells together into "sticks" for motor power packs. I still used it to solder power leads and cell interconnects onto A123 packs.

     The 25W iron below it was sacrificed to become a tool to open up pushrod openings and air flow openings in iron on coverings over balsa airframes.

     The middle iron is actually a high wattage 'leading' iron used for stained glass work. I used it to solder power leads and cell interconnects on NiCad and NiMH cells before I had a hammerhead tip.

     The K&S 60W iron, second from the bottom, was not taken care of and re-tinned after every use.

     The bottom iron was supposed to be a 60W iron. I picked it up from a vendor at the Toledo RC Expo for cheap. It was!!! The tip bent into a crescent shape on the first heating.

     With no decent flying weather at the end of April through the first part of May, and having at least a half a dozen soldering projects in the queue, I decided it was time to improve my soldering skills.

     One of the first things I ran across was an old (copy write 1998) Weller document on soldering.

     It presented a lot of good information about solder and soldering. If you need more background about solder and soldering, I recommend that you download and read the document. It provides a good reference regarding proper soldering, and WHY it is proper soldering.

     "I wondered why it was no longer on the Cooper Tools Web site. They were listed as the authors of the document. Some more research showed at Weller Soldering Products | Weller Distributor | Mouser www.mouser.com/weller/: "Weller distributor Mouser Electronics sells Weller soldering equipment. Weller is part of Apex ToolGroup (Formerly Cooper Tools)."

     "With a somewhat better understanding, I looked for soldering videos by Bruce Simpson (RC Model Reviews) on YouTube. He is my "go to" guy when beginning research on YouTube. After watching his videos about solder and soldering, I watched videos by other people on YouTube.

     "In the following section, I've presented Bruce's video segment first. It is followed by other video segments on the same topic, or that disagree with the information provided by Bruce.

     "The first annotated time indicates where into the video the segment will start and the second annotated time is where that segment ends.

Leaded solder 250-deg C to 260-deg C or 482-deg F to 500-deg F
He says that 280-deg C (536-deg F) is too hot

Another recommendation:
14:07 - 14:42


7160F for lead solder and 7250F for lead free, but he also says he uses 6500F for lead solder, but can run as low as 5500 F.

How not to solder
31:35 - 33:40

     After years of hit and miss soldering success with plug-in soldering irons, and poor technique, I decided to purchase a soldering station with temperature control along with several useful size tips for the type of soldering that I do in my RC hobby.

     Bruce Simpson uses a Hakko brand FX888. I noted that many of the folks in the videos also used a Hakko brand soldering station.

     I watched a complete review of the current Hakko FX888D by at Sparky's Widgets on YouTube.

     I checked out a few alternatives before purchasing the Hakko.

     There was an older version of a Hakko known as the 936. Hobby King sells a 'reengineered' version for $18.34.

     Bruce Simpson looks at the Hobby King version and shares his opinions.

     Dave Jones reviews this 'reengineered' version on his EEVblog.

     http://www.bestsolderingstation.net/ has ratings and reviews for soldering stations in the $50 to $150 range.

     The Weller WES51 also seemed like a quite usable unit with decent reviews.

     Both the Hakko FX888D and Weller WES51 analog soldering stations are available through the Home Depot Web site.

Hakko FX888D: $96.37
     The Web page says that no tips are included. That must mean extra tips, as the iron comes with the laser engraved T18-D16 installed, as noted on the Home Depot page. All real Hakko tips are laser engraved with the tip number. Counterfeits have the number printed on the tip.

Weller: $88.89

     I couldn't find tips for the Weller on Home Depot Web site.

     I ordered my Hakko FX888D through Home Depot. It is not carried in their stores. I assume that my unit came directly from Hakko USA, as the tape used to seal the shipping box had Hakko printed all over it, yet the packing slip was invoiced through Home Depot.

     I ordered it on April 27 and it arrived at 5:30 p.m. on May 4.

     Ordering it through Home Depot, finding Hakko tape used to seal the shipping box, having a colorful consumer information sleeve around the box containing the unit, noting a typical California warning label about lead dangers on the unit's box and the unit's box containing what appeared to be recycled fibers, allayed my fears of it being counterfeit. (See: "The Counterfeit Hakko FX888D Problem" near the end of this article.)

     The only piece of paper in the unit's box was the tri-folded Instruction Manual, in English.

     As usual for me, the print was too small for me to read comfortably, so I read the downloaded version, enlarged on my computer.

     After reading through the manual, I decided that I wanted to get started. I wanted to tin the new tip with 60/40 rosin core solder. In Section 7 of the manual, tip maintenance, it said to set the temperature to 4820F when soldering is finished, which was supposed to be the default preset number.

     I watched the video on initializing the presets and selecting them.

     The Instruction Manual noted the default preset temperatures in Fahrenheit degrees were 482, 572, 662, 752 and 842 degrees. That's not what displayed when I had set the base station to preset mode. They were set to; 600, 700, 750, 800 and 850 degrees Fahrenheit.

     I then had to watch "How To Change the Preset Temperatures".

     I set all five presets to the Fahrenheit temperatures noted as the default temperatures in the manual.

     Preset 1, now set to 4820F, was chosen and the temperature was allowed to stabilize. The tip was cleaned using the new sponge and distilled water and then tinned with the solder.

My Soldering Projects to Date

     Since then I have successfully soldered an XT60 to APP adapter, several wire extensions, several wires and 1157 light bulbs involved in my battery internal resistance research, two A123 4S 1100mAh battery packs and a cell replacement in an older A123 pack.

The Counterfeit Hakko FX888D Problem

     I previously mentioned that the 936, sold by Hobby King, was 'reengineered' and not a fake or counterfeit, as they did not put the brand name Hakko on the unit, even though it was 'implied' by the number.

     There are true counterfeit Hakko FX888D units available on the Internet, with a lot of them on eBay. They are produced to look exactly like the real unit and they are marketed as the real thing. The counterfeit units are mostly aimed at the 220V market outside North America.

     A quick search of eBay, from here in the U.S., showed two obvious counterfeit sellers of 120V units. One of the sellers was located in China and the other in the USA. It seems that most of the sellers of the FX888D on eBay use the same photos, and they are not the photos of the actual product being sold. The photos are no clue, but the price is a fairly good indicator.

     Luckily, eBay has a money back and no return necessary policy on counterfeit products.

     The following videos show what to look for when identifying a counterfeit Hakko FX888D.

From the Video "Fake Hakko FX888D on Ebay"

What to look for:
Fake iron shinny plastic, real one is more matte
Grip covers part of nob to get to heating element on fake iron, not on real
Loose fit on tip over heating element on fake, snug on real.
Yellow iron holder on stand of fake comes off and has no silicone ring, real doesn’t come off and has silicone in the holes from the ring inside.
Iron flops around in fake stand and fits well in real stand.
No rubber feet on bottom of the fake iron holder that are on genuine.
No grounding taps on the fake on the bottom of the iron holder.
Bottom of tray that comes off is metal on fake and release button comes off. Same item on real is plastic with aluminum insert and button is attached to it.
Can clearly see the segments on the LDC of the fake and not so on the real one.
Bottom plate of base station is a rough plastic with a sticker that doesn’t go all the way between the feet. On the real one the plastic is smooth and the sticker goes all the way across between the feet.
No rubber feet on the fake but are on the Hakko.
On/Off switch is loose on fake and not on genuine.
Fake has AMEL brand IC chip and real has an unmarked, in-house Hakko chip.
Programing pins on the edge of the main board are marked on the fake and not the Hakko.

From the Video "Hakko FX-888D - Real vs. Counterfeit - how to spot a fake"

Fake box it came in is not recycled material, even though the graphic shows it to be. Box for genuine is recycled as can be seen from flecks in it and 'wet newspaper' smell.
No metal insert in iron holder, and there is one in a real Hakko.
He does say die cast bottom on iron holder, which differs from above.
Strain relief on fake iron is hard and not flexible like on genuine.
Plastic on base unit cover is not smooth feeling like genuine.
His knock-off doesn't have fused daughter board on top of transformer and AMEL chip.

From the Video "Hakko FX888D unboxing 2"

David Taylor describes what happened to his fake and shows a genuine one.
Genuine has iron in top of box with cardboard over it. It is not in plastic and space is provided for the iron in the box itself.
Base unit not in plastic.
Aluminum tray visible in iron holder during unpacking.
Fake unit he had previously did not have the metal insert in the iron stand.
Noted that cord between main unit and iron is the good silicone, nice and squishy.
