It depends on the carbon polymer that the fabricator printed on your board. It could be: * No wave soldering * Wave soldering with a peelable mask * Wave soldering ... probably one of the latter two. Watch it. Some temporary masks can affect the

now we use Solder mask from peters.de but it too thick so we can't use process for screen epoxy

If you are not washing and want to stay with a peelable mask the two basic types are vinyl and latex. Although we've seen some silicone and urethanes, they cost more. * Do not use latex peelable solder mask with a low residue soldeing process withou

I think silicone mask is ok, This is so that after soldering, you can use these holes to fit other components later. This peelable layer is needed, unless you want to solder each component manually--From ALLPCB

Why don't you use peelable/washable solder mask on the SMT components next to the T/H pins? Then, you won't have to worry about keeping the tight tolerances.

We are planning on converting to a no-clean soldering chemistry and will need to replace our water soluble liquid solder mask as a result. Does anyone know of a dispensable, "peelable" solder mask I can evaluate? It would be nice to find one that i

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

Consider: * Changing your temporary solder resist [TSR] to a light cure. * Contracting with your board fabricator to apply the TSR. * Gaining better thickness control of your application process by silk screening the current TSR. * Forcing more air c

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.

burns and melts in the pot sending the solder golden/yellow and drosses like mad. Lackwerke pieters germany ( not sure on spelling) Lead Free version works well,if you need the exact code I will get for you. cheers greg york
