How to Reduce PCB Rework Cost Caused by Residue Left from Ordinary High Temp Masking Tape

Many PCB manufacturers suffer unexpected extra cost when cheap masking tape leaves sticky residue on gold fingers after wave soldering at 260°C. Residual glue leads to extra cleaning process, up to 15% higher production scrap rate and delayed delivery, which is a common pain for global PCB factories.

Lvzhimei, a professional Chinese manufacturer of PI & PET high-temperature tape, has helped one Vietnam-based PCB producer cut scrap loss by 21% after switching our silicone-based PI masking tape. Our tape stays stable under continuous 250~265°C reflow soldering, peels off fully clean without any adhesive leftover, and keeps consistent thickness tolerance ±3μm for precise circuit board masking.

Our core PI tape specs cover 12.5μm~125μm film thickness, available in customized width from 3mm to 500mm to fit different PCB production lines. All items pass REACH & RoHS certification to meet EU electronics import standard.
