U-Tg usho izinga lokushisa le-Glass Transition. Njengoba ukusha kwebhodi lesifunda eliphrintiwe (PCB) kungu-V-0 (UL 94-V0), ngakho-ke uma izinga lokushisa lidlula inani elinqunyiwe le-Tg, ibhodi lizoshintsha lisuka kusimo esiyingilazi liye esimweni senjoloba bese umsebenzi we-PCB uzothinteka.
Uma izinga lokushisa lokusebenza lomkhiqizo wakho liphakeme kunokwejwayelekile (130-140C), kufanele usebenzise i-High Tg PCB impahla> 170C. kanye nenani eliphakeme le-PCB elidumile lingu-170C, 175C, no-180C. Ngokuvamile inani le-Tg lebhodi lesifunda le-FR4 kufanele okungenani libe ngu-10-20C ngaphezu kwezinga lokushisa lokusebenza lomkhiqizo. Uma 130TG ibhodi, izinga lokushisa ukusebenza kuyoba ngaphansi kuka 110C; uma usebenzisa ibhodi le-TG engu-170 ephezulu, izinga lokushisa eliphezulu lokusebenza kufanele libe ngaphansi kuka-150C.
