Availability of corrosive and conductive particles of the flux or solder past may lead to jeopardizing the product reliability in spite of excellent workmanship. This may not be applicable to the non-clean flux/ solder paste but if the customer specify or supply consumable material with the RMA fluxes or VOC water based fl uxes then PCB washing becomes an essential process in the product assembly. PAC can offer PCB washing upon the customer request or from the selection of material by the customer specific applications. This can eliminate all the corrosive and conductive particle of flux from the product assembly. Ionic contamination can also be verified and reports can also be provided to the customer on request.
