HOW LONG DOES IT TAKE TO BE ABLE TO STACK 7135 CHIPS?I DID IT :stacked 4 each 7135's

Lj,

Oh, I forgot about this video that O-L did awhile ago:

A video on soldering 7135 chips to a NANJG driver

This is just my method. Others have different methods. The method I use, to hold the chips on the driver for soldering, is the real reason I wanted to share the video. [Adding 7135 chips to a NANJG board] The "Hemostats" talked about in the video, are properly called "Allis Tissue Forceps" and they work fantastic for holding the chips in place, while soldering. They are very expensive, but the link above will show some "budget prices". I have always had "issues" with solder…

I actually bought one of those Allis forceps (Amazon.com) after watching O-L’s video, and have used them for quite a lot of things, like holding things together when I’m soldering them. I haven’t tried using them with 7135s like he does in the video yet, but it looks like that would solve one big problem I kept having, where the 7135 wouldn’t stay in place while I was soldering it.

FYI, I also had cateract surgery earlier this year on my one good eye, and it’s taken me awhile to get use to my new “eye”, so I’ve accumulated different type of glasses, etc. :(, and I got one of these which was very helpful, because you can try different powers vs. focal distance:

Good luck!
