Mikeh: You can't let that stuff get to your carbon bed. Literally, you can watch your bed die. The clay coats the carbon, entombing it. I've heard talk of using a RO filter as a front-end buffer to the recycling system, but know of no one who has

Water soluble masks are great in my book. After having used the latex type, I found that the water soluble will save a lot of time. I dont't use a closed loop system, but I do have a filter on my discharge line. I have not experienced any filter c

Hi, We are in the way to evaluate different solder pastes, improve our solder paste incoming inspection steps, re-define our stencil requirements and the following questions are open. Two questions, 1- Is anybody using/requiring 1000 Kcps or more

We have a local shop here in S-Cal. called MaskTek that invented a solder deposition process that eliminates the need for solderpaste but you still need to use "sticky" flux. They license the process to various facilities around the country. Was pr

Folk's, I'm just tying up some loose end's on my Master's Thesis on solderballing @ wave soldering and the effect the topography of the mask / PCB has on it. I was wanting to do a straw poll on you guy's as to the type of resist's you are using Glos

I have a board, 4 spacers needed to be soldered on the board first with the normal 62Sn37Pb alloy. Then, capacitors are manually soldered on the boards. The density of the board is quite high. If we wave soldered capacitors first, there will be no p
