You don't have pliers, Chuck ? I hope, that in next time wires will be better angled....

 

[Chuck911]

UE: What? Which wires? Is this a joke?

Here is my joke:

An externally hosted image should be here but it was not working when we last tested it.

Photo of PA isn't your ?

 

[Chuck911]

Which photo of PA? I don´t understand. You´re pulling my leg. I really don´t like it.

This is mikes board. From his sites. I only use it for demonstration for henrik.

Hi Mike,
With the kind assistance of Clem, another pair are coming to life. Clem was kind enough to make some boards, he sent me two of them.

This one is waiting for parts, then measurements before I finish the other one. Those darn capacitor sizes!

I'll report when done.

The foil side has been coated with solder.

[Chuck911]

Guys how did you coated boards with solder like this? That look almost like HAL.

 

[anatech]

Hi Chuck911,
It's very low tech. Coat a section with liquid solder flux (for electronics). Put a few dabs of solder on the traces in the area. Use solder braid and your iron to coat the traces.

Hot dip except it's really hot drag. Clean with lacquer thinner.

[Chuck911]

Yeah this is fine idea. I must try it for my homemade boards. I hope that I can find our old iron.

I was thinking about heating PCB with some solder in kitchen oven and use something like wipe to wipe off waste solder. But IMO your idea is better. Thanks.

Cheers

Chuck

I think those new caps are
Audyn-Cap KP-SN

 

[Chuck911]

May be but look at the picture in the sheet in Czech language here. In this sheet is original ES made caps. I must ask them. But i dont thing this is important for me.

Clean with lacquer thinner.

-Chris

!!! I was with you until right then! Isopropyl alcohol (purer = better) is all I ever used to clean solder flux and it works like a champ...

Hi Chris, that's good news, i am looking forward to your impressions...
Good work with the boards, but what is "solder braid" ?

Mike

 

[Chuck911]

mikeB: IMHO braid of copper. That is used to suck out waste solder when you need to get out bad device from PCB.

That can be used as something like wipe and distributor for solder for "home HAL".

New technical term: HIL - Hot Iron Lead
