Printed Circuit Boards (PCBs) are the “brains” of electronics—but in Southeast Asia’s humid factories, moisture causes copper traces to oxidize, leading to short circuits. A Vietnamese PCB manufacturer found that 8% of boards failed quality checks due to humidity damage, delaying orders for global clients.
Guangdayuan’s PE Black-White Film is a PCB protector designed for tropical humidity. Its multi-layer structure includes a special moisture barrier layer with a WVTR of 0.2g/(m²·24h)—lower than the industry average of 0.8g/(m²·24h). The film also has a dust-proof design: made in a 100,000-class clean room, it has fewer than 10 dust particles per square meter, avoiding dust sticking to PCB circuits.
For PCB manufacturers: we offer ultra-thin films (0.04mm-0.12mm) that fit automated packaging lines, and can punch holes to match PCB mounting holes. Our film is also heat-resistant up to 80℃, surviving Malaysia’s factory temperatures. A Singaporean PCB firm increased pass rates from 92% to 99.5% with our film. Guangdayuan PE Black-White Film keeps your PCBs functional, even in SE Asia’s most humid months.#//www.petprotectivefilm.com/en/contact-us.html# #PE Black-White Film#
