However, flexible plates are not completely flexible. Waɗannan PCBS suna da wasu yankuna masu tsauri, amma galibi ana ɗora kewaye akan sassa masu sassauƙa, don haka ana iya daidaita shi gwargwadon samfurin.

Yawanci polyimide yana amfani da tsarin THT (ta rami) don hawa ɓangaren, wanda ke nufin zaku iya amfani da gefe ɗaya don daidaitawa da canza sashin. PCB mai sassauƙa mai gefe ɗaya tare da ko ba tare da rufin garkuwa ba za a iya ƙera shi ta amfani da fim mai ruɓi; Koyaya, yin amfani da murfin garkuwa akan da’irar shine mafi yawan al’ada saboda yana hana kewaya da kowane EMI. The structure and insulation of a single-layer flexible PCB are explained as follows:

2. Application:

Ana amfani da PCBS masu sassauƙa a fannoni masu zuwa:
