如何评估PCBA板卡加工难度Issuing time:2022-11-01 15:15 PCBA的加工难易程度是相对与常规的PCBA制程能力来说的。
主要可以从3个方面评估: 1、PCBA主要的加工工序; 2、是否存在有特殊的工艺要求,如COB/Washing/Coating/Potting/Underfill等特殊工艺。 3、PCBA上零件种类。如0402以下的离散器件,Fine pitch IC 等都会对加工设备有较高的要求。 总体来说,建议通过DFM初步评估(Gerber,BOM,Drawing等文件的review)后,基本可以得出PCBA加工的难易程度。 在前期的DFM报告中,可以给客户建议设置测试点,以便焊接好的PCBA样板,测试电路导通性。 Declaration: This article is originally created by the editor of Guangzhou Dingchang Electronics.
