PCB Peelable Mask: The Protector Behind High-precision Manufacturing
As electronic products become increasingly miniaturized and complex, the accuracy and reliability of PCBs have become crucial factors in determining their survival and development. In this intricate process, there is a seemingly inconspicuous yet critically important component — the peelable mask. Although it may not as eye-catching as chips or components, the peelable mask plays a vital role in the production and protection of PCBs. What is PCB Peelable Mask ? PCB peelable mask is a special adhesive material that often used in PCB manufacturing process and appears blue or light blue. It mainly used to protect, secure and insulate specific areas. For many high-precision PCBs, the use of peelable mask directly affects the product yield and performance. Four C ore F unctions of Peelable Mask 1.
