摘要

本文介绍了一组实验，研究了与传统材料相比，由可生物降解的可持续聚合物制造的多氯联苯的机械性能。实验中比较了醋酸纤维素(CA)、聚乳酸(PLA)和阻燃4级(FR-4)底物。测试方法包括动态力学分析(DMA)、三点弯曲试验和UL 94可燃性试验。初步结果表明，与FR4板相比，基本的可生物降解、可持续的多氯联苯的整体性能要弱得多，然而，添加剂的进一步改进和在特殊应用中的使用可以指出基板的实际用途。

Investigating mechanical performance of PLA and CA biodegradable printed circuit boards

The paper presents a set of experiments investigating the mechanical performance of PCBs manufactured from biodegradable, sustainable polymers, compared to conventional materials. Cellulose Acetate (CA), Polylactic Acid (PLA) and Flame-Retardant Class 4 (FR-4) substrates were compared during the experiments. The methods involved dynamic mechanical analysis (DMA), three-point bending tests and UL 94 flammability tests. Preliminary results show that the overall performance of the basic biodegradable, sustainable PCBs are considerably weaker compared to FR4 boards, however further improvements with additives and use in special applications can point to practical purposes of the substrates.
