It’s been concluded that 70% of manufacturing cost is determined by design issues and manufacturing including overhead, material and labor cost only accounts for 20%. Thus, design counts. That also works in PCB (Printed Circuit Board) production. Circuit designers come up with their designs based on their unique thoughts and function expectations of end products. However, they care little about manufacturing. Once improper elements are directly used on manufacturing line, defects will definitely be caused. Worse still, some designs are never manufacturable. All the above issues indicate the significance of DFM (Design for Manufacturability). Cable assembly manufactured by Absolute Electronics Services. We provide quality and efficiency in cable production and assembly. Contact us today! Actually, DFM does help you to reduce the cost of PCB fabrication and increase the reliability of PCBs. You can NEVER miss it. What Is DFM? Design for Manufacturability for PCB is also a part

Lead-free PCBs (Printed Circuit Boards) were first called for just for the compliance of ROHS (Restriction Of Hazardous Substances) by EU (Europe Union) that requires all the electronics have to conform to ROHS regulations. As a result, PCB fabrication starts to convert from lead to lead-free. The lead in solder joints mainly derives from plated pins of components, PCB plated pad and solder. To ensure the lead content in solder joints conforms to ROHS regulations (mass fraction should be lower than 0.1%), surface finish applied on PCBs, therefore, has to be lead-free compatible. Right now, a couple of surface finishes have been generated for the achievement of lead-free fabrication and ENIG, ImAg, ImSn and OSP are most widely applied. Since each type of surface finish features its own advantages and disadvantages, it’s important to be clear which type of surface finish is optimal as far as your projects are concerned. Thus, this article will compare the four types of surface finishes
