Temporary Masking Solutions: Tecnite EP25K and EP50K Kapton® Tapes!
During wave soldering, all PCB components (through-hole and SMC) and all plated sections (vias) are either soldered or sealed.
Some components, such as lands, cannot withstand this step due to mechanical, thermal or other reasons.
They must therefore be masked and soldered at a later time.
This masking can be done using synthetic peelable coating mask (Electrolube® PCS) and a new product: Kapton®
EP25K and EP50K tapes are high-temperature tapes made from Kapton® HN film with silicone adhesive.
Each roll is 33 meters (108 feet) long and comes in two backing thicknesses (25 µm and 50 µm).
