    Printed Circuit Board Etch Resistant Marker Pen

     1,000

    This two sided etch resist pen for fast fabrication of printed circuit boards. The ink adheres perfectly to copper and is completely resistant to ferric chloride and other usual etchant solutions. Draw the planned circuit onto a thoroughly cleaned copper laminated board and allow to dry. Then immerse the board in etching fluid until the copper is dissolved. The ink can then be removed with Degreasing Solvent or PCB Cleaner, and the circuit board is then ready to be drilled and assembled. This pen is capable of producing thin, delicate lines allowing for quite a condensed track layout if required.

    It can also be used to correct broken tracks while making PCB using toner resist method
