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...

If you think of spot mask as basically liquid masking tape, the application become more intuitive: 1) Apply the mask to the contact areas to protect. Allow mask to fully cure. 2) Apply the conformal coating. 3) After the coating is dry to the...

Spot mask can be hand applied, dispensed with a pneumatic system, or stencil printed. To hand apply using a squeeze dispensing bottle: 1) hold the mask bottle upright, but at an angle (around 60°), 2) squeeze the bottle as you drag is across...

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....

Chemtronics offers the CircuitWorks® Rubber Keypad Repair Kit, which can be used to repair keypads by restoring conductivity to worn, intermittent, and nonconductive carbon contacts. It is a 2-part mix, and comes with a swab, brush, and plastic...

CircuitWorks® flux pens are available with a variety of fluxes to fit your specific shop requirements, including: no-clean, high temperature no-clean for lead-free soldering, rosin, and water soluble. Flux pens are an excellent way to dispense...

This answer assumes the crack does not impact surface or inner-layer traces. CircuitWorks Overcoat Epoxy provides a rugged repairs that can actually reinforce PCB areas with more structural cracks.

Standard 2-part epoxy can contaminate the surface of the connector, creating an insolative barrier. 2-part conductive epoxy is a great solution for making repairing damaged pads. This type of epoxy contains conductive material, so when cured,...

CircuitWorks Conductive Paint is a single component, silver-filled polymer that dries in minutes at room temperature, making it an ideal solution for patching EMI/RFI shielding. The kit comes with brushes, swabs, and a plastic pick to repair...

A common method of repairing a broken trace is to solder on a jumper, which is basically a wire bypass around the broken trace. This can be time-consuming and visually unappealing. Chemtronics offers CircuitWorks® Conductive Pens, which contain...
