The latex should not influence your closed-loop filtration - unless of course it falls off during cleaning. The issue would be with water soluble materials. As Dave (hi Dave) said, the clay based version of these will clog/blind/knacker your carbon

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

Jeff In my experiance the main problem is the flux content of the paste (up to 50%). throwing it in the wave pot results in a big stickey ring around the pot, a lot of smoke and, as Brian says, a lot of dross. A fire is not that unlikely! I tried

John, I'm sure your right! Cause my partner is laughing at me over the idea. "How often do we want HazMat at our door" "Do we really want to be friends with them on a first name bases" " Do we want to make friends with their friends,OSHA" I still thi

Hi everyone, I am having a problem with cleaning PCB's with different finishes. I run one type of board through a drag solder and it comes out perfect using a water slouble flux then putting it in an aqueous cleaner. Then I run another board with a d

Hi, We are using mixed technology in our PCBA. Would like to know whether there is any criteria governing/guiding the use of mixed technology in such aspects as: 1. Some SMDs cannot be used in some kind of PCB materials such as FR1? 2. Some SMDs are

Hi all. I have some experiance in regular electronics, but the hardest part for me was always the soldering, so I am very intrested in SMT. So what would be the best way to get started in SMT? I would prefer not to have to spend alot of money, but

Hopefully, everybody suffers from solderability of SOT-23 devices and I would like to know how everybody else resolves this problem. Historically, here, we have always gone for 6 thou stencils. I found that going to an 8 thou stencil improved the sit

I have an adhesive dispenser in my workcenter but I rarely use it. I've replaced this process with wavesolder pallets for bottom side PTH soldering, ocassionally gluing parts left exposed by the pallet. So I was thinking of selling the dispensing equ

Yes. We use high speed dispensing (PanasonicFA)as an integral part of our PCB assembly. Our business is automotive electronics and our typical product is 2-sided smd with some through hole. We assemble topside first, through hole, then bottomside. Th
