We are considering using gold plating on our fine pitch pcbs (as oppossed to HASL). We have heard of long term solder reliability problems with joint imbrittlment how bad is this and does it apply for all of the different plating processes the same?

I have been earnestly seeking out a resource from whom I might purchase used Philips feeders for the ACM line. Due to its relatively recent introduction into the market, these are rather hard to find, and have not had much luck going through Philips

My company manufactures a board for a heavy duty automotive application. One of the through hole parts on the board dissipates enough heat that it requires high temp solder. Does anyone know of or have experience with a high quality selective solde

John, Ahhhh the possibilities. Have you considered the dissipative properties of available substrates? A ceramic (excellent heat dissipation) based substrate could be a possibility for future designs. Maybe there are surface mount parts out there fo

If your feeling really flush with ash you could contact your wave machine vendor and buy some from them. But I have to admit I do prefer Dave's idea...much cheaper, you'll get it in some kinda timescale rather than the 4 week's your machine vendor wi

Hi all, I am trying to find websites for inline aqueous cleaning equipment. I have found Trek, Austin America, Electrovert, and Aqueous Technologies. I can't seem to find any others. If anyone knows urls for others I would appreciate it. And yes

That's cool that you used the Archive. Consider running a designed experiment on your board, using your flux and solder, the limits from the Archive, and on your machine to dial in the spread in dwell numbers you see in the SMTnet Archives to your s

We are using Austin American Technologies with Petroferm solutions and have excellent results using the same two types of solvents for cleaning stencils, adhesives and miss print boards. I average about five hundred cleaning cycles before we have the

Mark - The Waverider is a great tool. It will let you know what's going on with the machine itself - contact time in the wave, parallelism of the wave, temp, and a relative idea of whats happening in the preheat section, and conveyor speed. We hav
