Hello gen, Is there any recommendation of a liquid flux for SN100 solder bar on wave? Appreciates!

Spray or foam? Are you looking for IPA or Water based?

I got an inquiry from one of our electronics labs with regards to their soldering processes. They use eutectic (63% Sn, 37% Pb) solder. For liquid flux they are currently using Kester 186, which is an old-school, full rosin (RMA and ROL1) flux that c

I am looking for a consistent method of applying no clean liquid flux to solder pads. My main concern is if I use a standard air-over type dispenser mounted to an automated arm that the liquid flux will make a mess and not be consistent. I'm not to

Why are you placing Kapton dots on your board prior to wave soldering? * Prevent solder from touching the hole and the area around it. [If so, why do you need to do this?] * Prevent solder from flowing up through the hole and coating portions of the

You can also insert a stainless steel screw the size of the hole in the board before wave soldering, this will prevent the solder from wicking up to the top or close the hole (this is real cheap). I still remember the good old days using toothpicks t

We'd contact suppliers of LPISM. Top LPISM available in the United States are: * Coates ImageCure XV501T & XV501TSM * Coates ImageFlex (Flexible Solder Mask) SV 601T * Enthone DSR 3241 and DSR 3241 GM * Rogers RFlex 8080 LP1 & RFlex 8080 LP3 (Flexib

From what I can gather, the annular rings are used for grounding when these boards are put in housings. A screw goes through the hole and is torqued down. If there is excess solder on the annular ring, the screw doesn't seat properly. The pallets cov

Is the peelable mask (put on by the boardhouse) flat on the surface of the pcb? If so can you tell me the material name, so maybe I can find a picture? We have to print adhesive on the board, so the mask has to be flat. That is why Kapton from the b

Besides the solder mask suppliers, I would contact some makers of exposure and alignment equipment. Try OLEC (www.olec.com) - they make different types of expsoure equipment. Another good source is a company called All-4-PCB (they rep a number of P
