Hello, our products are made on single-sided boards and we often have problems with receiving too warped PCBs from our suppliers. Can anybody suggest a good laminate or the most important properties of the material so we could specify it when we orde

Hi Dave sorry not been back the Tin/P regenerator is controlled amounts of Phos additive that metallurgically reduces the dross. We do not recommend chemical methods for dross reduction as many salts/chemicals used could be hygroscopic in nature and
