What film do people use to check paste alignment on PCB's? We used to use a mylar but it is now obsolete and the last stuff that we ordered was more like cling film.

Help!! Just got some new wave solder pallets in house. The pallets are 12 by 8 inches solid composite, with only two 1/2 inch by 1 inch spots cut out for the connectors. When they go over the wave, the solder wants to cling to the bottom of the pal

If they don't come within 12 inches of ESD sensitive material, would it matter? Although to be honest it would still make me nervous. Anytime you see static cling, you have the potential for ESD. (pardon the pun) Also if you see dust or other fine m

Esoderberg, Thank you for the response! I was completely unaware that HumiSeal provided latex masking. I have a sample on the way. I sampled some Wondermask 2211 in the past. By the TDS description, I wonder if they share the same makeup; both

Sounds like the mask to me. Had a similar situation a couple years ago. The mask wasn't fully cured, so it absorbed water that the preheaters couldn't dry out. When it outgassed at the wave, it caused a lot of micro turbulence that broke the surfa

Hi Again Distance is tough, besides far less exciting.. You got the panther at your breast, screaming!! Somehow you have to make this go the other way. Rather than solder flowing any old place it wants to, when it wants to. Chasing the heat, Chasi

Just thought of something while on the beach. We made a paste change several years ago when we installed another surface mount line. At around that same time, our maint. crew changed chain oil and about 2 months later changed when they oiled the ch

| I'm in the process of moving from water washable flux to a full no clean process for the wave soldering process, thing's seem to be going well (so far...). | The one problem I still have is cleaning the wave solder carrier's to remove the no clean
