Like many others, I have had issue soldering drivers to pills. Normally, the solder does not stay hot enough to properly stick to the pill. This results in overheating the pill/LED before a proper bond. After A few p60 drop-ins, I have now figured out a simple way to fix this.
I tin the pill before any components are added using a torch. This allows me to heat the pill as much as needed and to get the solder to really stick.
I know it’s a simple solution, but it was something I didn’t think of before.
Tinning the pill before adding components is a good tip.
But I have to say, I’m a little baffled by the number of people who have trouble soldering the driver to the pill. I use a pretty basic Radioshack 25W iron and even with my admittedly remedial soldering skills, I have never had problems getting solder to adhere to the pill. I wonder what’s going on.
For a high-thermal-mass part like a P60 Pill, the two most common problems are going to be
1) Lack of Flux - Either not using any or burning it all off before the pill gets to soldering temperature
2) Too small a Soldering Iron Tip or Too Low a Wattage Iron. Both yield the exact same result - you can't get the place you're trying to solder hot enough. With a 50 Watt soldering station and a good spade tip, I can solder a driver to a pill in less than 5 seconds per connection point.
I think it would be better if someone (preferably one of our resident experts) discuss how tinning is being done. :~
I’ve seen OL’s video at YouTube (can’t find the link because I can’t access YouTube right now) and it is very helpful especially to BLF members who are new to soldering or who are still contemplating on starting their own mods.
