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

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

Shane: We don�t dispense, but we have thought about it. Several points about peelable solder masks in a no-clean (low residue) process: � Beware of latex peelable solder mask with a low res process without extensive testing. The problem is usuall

Is there a peelable solder mask which can withstand an automated aqueous wash ? I need to prevent water ingress into SMT modules during the wash cycle.

I have gold fingers that I want to mask when running over the wave without pallets. They're on the leading edge of the board. I recall seeing rubber boots that slid onto the fingers to mask them. Pop 'em on before the wave; pop' em off after and r

We have an application where an assembly has to be residue (flux) free except for 2 SMT non washable parts. Currently those parts are post wash hand adds but the product volume is exploding. We want to run those parts in SMT, mask them using an aut

Hello everyone, Has anyone had success dispensing ammoniated latex masking using a valve? If so, what company and type of valve are you using? Our current supplier of non-ammoniated latex masking will no longer provide a container larger than an 8 o

We prefered kapton tape to peelable mask, though, there is added time/effort to taping the boards, then removing the tape (if it's done hot, it can go pretty quickly). If you're at a volume where manual masking/mask removal is too time consuming, co

Shorted to the sheild or the BGA balls are shorted? Sheilds move a lot during reflow. If this is the case, place some adhesive or peelable solder mask on either side of the shield and baords to stop it from moving.

I have considered this solution, but syringe application is very slow and it's hard to control thickness. It's good for partial covering or applying peelable solder mask. We need to coat circular board ca. 10cm in diameter. Takes a while even with sp
