Application
PCB Masking (Primary Application)
Used in wave soldering, reflow soldering, and gold finger protection to prevent solder contamination on critical areas.
Powder Coating & Plating Masking
Ideal for masking during high-temperature powder coating and electroplating processes, ensuring clean and sharp edges.
The Role of 0.025mm PET Tape in PCB Powder Coating & Protection
In the high-precision world of Printed Circuit Board (PCB) manufacturing, every micrometer counts. STK's 0.025mm ultra-thin PET tape is specifically engineered for high-temperature masking during the powder coating and gold-plating processes. The "Ultra-thin" characteristic is not just a dimension; it is a functional requirement. By utilizing a 0.025mm polyester film backing, engineers can ensure an incredibly sharp, clean paint line without the "edge-lifting" or bulkiness associated with thicker tapes.
During powder coating, the PCB is often exposed to curing temperatures exceeding 180°C to 200°C. Our heat-resistant polyester film maintains its structural integrity under these thermal stresses, ensuring that critical connection points, such as gold fingers and mounting holes, remain perfectly shielded from overspray and contaminants. The high-performance silicone adhesive provides immediate tack while guaranteeing zero residue upon removal-a critical factor for downstream assembly and electrical connectivity.
Beyond simple masking, this tape acts as a barrier against aggressive chemicals and solvents used in the industrial coating environment. As a manufacturer with 20+ years of expertise, STK Tape understands that inconsistency in tape thickness can lead to batch failures. Therefore, our 0.025mm series undergoes rigorous tension and thermal stability testing in our state-of-the-art labs to ensure that every roll delivered to your production line meets global industrial standards.
