How High of a Temperature Can Temporary Solder Mask Withstand?
Solder mask is engineered to withstand molten solder temperature for the very brief time (about a second) it is exposed in a typical wave soldering process. Most commercially available masks should be able to withstand melting point temperatures...

Can temporary solder mask be left on the PCB permanently?
Temporary solder mask is intended to be just that – temporary. Manufacturers of solder masks, like Chemtronics, always recommend removing the mask because there is no testing to support doing otherwise. If you decide to leave the solder...

How do I remove temporary solder mask?
Washable mask is engineered to be removed in an aqueous inline or batch wash system. If you are using a closed-loop system, which filters and recirculates wash water, make sure you use a mask that is compatible with your physical filters and...

How do I remove temporary solder mask?
Peelable mask is usually removed by hand or with tweezers. Resourceful engineers have come up with devices with rotating brushes and other creative methods, but there is no commercially available equipment to speed this process along.

How can I prevent solder mask from breaking off in the through-holes?
Believe it or not, the way you hold the bottle can make a big difference on how easily the cured mask is removed. Many operators hold the bottle at a 90° angle as they drag the dispensing tip across the area they are masking. This has a...

How do I use temporary solder mask to protect contacts from conformal coating?
If you think of spot mask as basically liquid masking tape, the application become more intuitive: Apply the mask to the contact areas to protect. Allow mask to fully cure. Apply the conformal coating. After the coating is dry to the touch,...

How to I apply temporary solder mask?
Spot mask can be hand applied, dispensed with a pneumatic system, or stencil printed. To hand apply using a squeeze dispensing bottle: Hold the mask bottle upright, but at an angle (around 60°). Squeeze the bottle as you drag is across...

Is there a good way to remove labels and sticky residues?
Old identification or QC fault labels can be difficult to remove. They either leave sticky adhesive behind that is insoluble by commonly available solvents like isopropyl alcohol (IPA), or are so dried and baked-on that they won’t budge....
