SD202 high temperature tearable solder mask, natural glue paste solder mask

 Model: SD202 High Temperature Tearable Solder Mask

Characteristics: High-temperature tearable solder mask is composed of natural glue, which is a new type of solder mask product that replaces traditional high-temperature tape. It is applied to the coated area of the circuit board until it is to be removed, and it can be gently removed by hand or tweezers, leaving no adhesive residue, and the short-term temperature resistance is up to 280°C. It will not oxidize gold, copper, phosphorus and bronze, do not corrode parts, prevent pollution during assembly, do not stick to tin, do not explode tin, can be completely decomposed by microorganisms, and meet environmental protection requirements.

 Environmental protection requirements: in line with RoHS directives and related environmental protection requirements
