My tin setup is Sulfuric based, Tin stuff and Brightener The Tin is pattern plated at 100 milliamps per sq in (.0001 per 10 mins) I shoot for 0003~0004 " My...
I just used GerbMerge to order from AdvancedCircuits. It only tested with Eagle produced gerbers. So far no problem, but my order is not done yet, so I'll keep...
Jeremy, Thanks for the info, I assume your plating solutions (including flash plate) were purchased as proprietary products. so I understand why you wouldn't...
My chemistry is for Tin/Lead (it' all about the organics, which I called brightener thinking of Bright tin which my kit was originally purchased as) This is...
... Ok, that clears up the confusion. If you say it contains sulfuric but can also plate tin/lead so then the it must have some other electrolytes for...
Actually I was wrong about the tin bath. Its not mixed with sulfuric, It's just water. It was too early for me. . The Bright tin uses sulfuric, and the etch...
... purchased as) ... try it ... quick rub ... Jeremy, If you dip the tin-lead plated panels in straight peroxide (30% or stronger) for 15 or 20 seconds you...
My last post must been sent just prior to yours. I actually ended up completely closing up some holes with the acid copper. It' definitely a more aggressive...
Thanks for the tip - I'll mix some up tomorrow morning, and err... figure out a place to put the new pre dip . JT http://www.soundclick.com/jtsound <snip>...
... Does that mean the alkaline plate was more capable of completely covering the holes walls with copper than compared to acid copper plating ? Which bath was...
Hard to say - and subjective at best. but IMO yes. We can discuss this more tomorrow, I've been trying to take some pics , but man is it difficult to even get...
Message for Adam and/or Tom, But open to anyone (Those two just have made it known they've done some higher volume processing) What would you suggest for a...
I use a shear. Very clean and fast. It makes a complete mess of phenolic but FR4 is very clean. I dont use phenolic except in emergencies so it doesn't...
carbide blade in tablesaw --> great. edges like polished, and straight.. or a shear, but the handheld sheetmetal shear bends the board slightly.... ST...
... slightly.... Agreed, I use a floor mounted 30" sheet metal sheer. flat bed, straight cut. definitely overkill but I have it for other things as well....
I've seen this done and was wondering if anyone has some words of wisdom as to how to do it. Basically, I want to attach a ribbon cable directly to a PCB....
I've done 0603's .5mm pitch TQFP's, various leadless packages and even the tiny 1mmx0.6mm SSSMini2P that Panasonic makes diodes in. Surface mount is not hard...
You could try simple pads along the edge of the board and solder the stripped wires directly to the pads. This will give you the clearance and is easier than...
Dremel = ++dust I have used a paper shear, but its a bit of a strain. A metal shear is just the ticket. You might be able to use one at a local sheetmetal ...
Ok, thanks for your response. I thought you might have had made a grand discovery in getting through holes to place reliably over carbon coated holes. As I...
I think it really has to do with the balancing chemistries. , or the organics. The Flash I'm using has no cyanide, I was under the impression that the...
