张**( 5***5G ) (0)您好，FR4的耐压各层间的耐压参数，就是30KV/MM,是多少厚度就按这个去折算（考虑到实际生产过程中厚度公差+/-10%的原因，一般的0.1mm耐压2700Vj是可以的）询价下单交货开票需要协助的可以点击下单主界面左上方“人工客服”图标－“PCB/钢网/SMT业务咨询”，找到您的服务专员联系处理。谢谢！<style> @font-face{ font-family:"Times New Roman"; } @font-face{ font-family:"宋体"; } @font-face{ font-family:"Calibri"; } p.MsoNormal{ mso-style-name:正文; mso-style-parent:""; margin:0pt; margin-bottom:.0001pt; mso-pagination:none; text-align:justify; text-justify:inter-ideograph; font-family:Calibri; mso-fareast-font-family:宋体; mso-bidi-font-family:'Times New Roman'; font-size:10.5000pt; mso-font-kerning:1.0000pt; } span.msoIns{ mso-style-type:export-only; mso-style-name:""; text-decoration:underline; text-underline:single; color:blue; } span.msoDel{ mso-style-type:export-only; mso-style-name:""; text-decoration:line-through; color:red; } @page{mso-page-border-surround-header:no; mso-page-border-surround-footer:no;}@page Section0{ } div.Section0{page:Section0;}</style>
