Lead-free products PCB design necessity

Lead-free products PCB design necessity

So far, although the country has not put forward special requirements for lead-free PCB design, there is no industry standard but advocates for environmental protection design that we need to consider the design ideas in terms of material selection, manufacturing, usage, recycling costs, etc. Which are consensus among us.
When implementing lead-free PCB manufacturing, designers should always pay attention to DFM issues, board surface plating options, laminate material selection and through-hole considerations, component selection, reliability issues, and After (Sn-Pb solder is soldered to lead-free components) and forward (lead-free solder is soldered to conventional leaded components).

 

For the pad design of lead-free PCBs, there are various sayings in the industry, and some arguments are worth discussing. One believes that lead-free pad designs can be smaller than leaded pads due to poor lead-free wettability (spreadability); there is also another belief that lead-free pad designs should be larger than lead. How to design the specifications and pads of lead-free PCB boards, pcb manufacturers will give corresponding suggestions and measures before the production of pcb products, but due to the gradual withdrawal of leaded technics, the design of lead-free pcb pads will be more perfect. More in line with production requirements.
