Guys Does anyone have any bright ideas with regards to masking a PLCC socket with via holes directly below the socket, prior to conformal coating ? We've tryed kapton tape and peelable masks but not with desirable results. Our coating process is a t

You know you'd think that wouldn't you but the only tiem I knew the vendor had changed something was when the silver started to fall off the boards!... you can tell I wasn't chuffed Now I have to say I do prefer Dunkin's to Krispy but I can't say I'

You can buy pre-made dots if that helps, they usually come in sizes from 1/8" on up. I have use a lot of temporary masks and no of none of them that cures quickly. I am sure that you know the thinner it is applied the quicker it cures. Have you e

Of course when it gets too thin it becomes difficult to remove! D^%#$'d if you do, D!@#'d if you don't. I agree with Jerry we also run the stuff semi wet when we have to. Do you have the possibility of getting these masked prior to assembly like t

Hi Amejia, Do you can try my silly idea by using some connector header with plastic holder type cut and preparation by number of pin same as number of hole you want to mask and insert thru the pcb hole before you coat or may be you can use some type

Peelable solder mask works well. Hand dispense and peel off after. Paint sticks work OK, but it depends on the mfger of the paint stick. In both methods you hand apply after screen print. Your Dek can be taught pads to get by. You may have to te

We've used masking tape and peelable (pink) mask to mask our boards before conformal coating for a long, long time. This is a huge time sink, and increases our lead times (particularly because of the cure time for the pink mask). What are other com

How thick are their requirements? A barrier can be made using peelable latex. That would then require manual or automatic dispense of latex to create a dam. Then you should be able to use an automated dispense system with a large orifice and flood

Hi, We are currently using WonderMask PX Peelable Solder Mask # 2222 for the wave rework process, but we are having a lot of trash in the pot. I understand that it is because the solder mask resists the pot temperature (500F) but not the rework tim
