Frosted PP Sheet

Frosted PP Sheet is a cost-effective Polypropylene (PP) solution for PCB/FPC protection during storage and transportation. Its frosted surface prevents scratches, while optional Antistatic PP Sheet design meets ESD requirements. Available in Green PP Sheet, blue, and custom colors, with 0.35-2mm thickness and flexible size customization. Paired with our PVA Sponge Roller for cleaning, it ensures PCB quality and reduces waste.

As a core accessory for PCB manufacturers, Welltronics PCB Separator Sheet with Frosted Surface solves the pain point of PCB scratches caused by direct contact. Made of high-purity PP material, it balances durability and cost-effectiveness—essential for mass production. The frosted surface enhances friction to keep sheets in place, avoiding slippage during stacking, while the smooth edge (with optional round corners) prevents damage to PCB edges. We also offer Antistatic PP sheet variants, critical for protecting sensitive components from electrostatic discharge, perfectly matching the quality control needs of lines using CMI500 Hole Cu Thickness Tester.

• Material: Food-grade Polypropylene (PP), non-toxic, corrosion-resistant

• Thickness: 0.35-2mm (0.5mm most commonly used)

• Surface: Frosted/matt (anti-scratch, anti-slip); mirror smooth optional

• Color: Green PP Sheet, blue, yellow, pink, purple, red, orange (customizable)

• Standard Sizes: 18″”×22″”, 21.5″”×24.4″”, 22″”×24″”; custom sizes available

• Edge Treatment: Sharp or round corners (free round corner customization)

• Antistatic Option: Surface resistance 10⁶-10¹¹Ω (meets ESD S20.20)

• Weight: 80-450g/piece (varies by size and thickness)

• Packing: 100pcs/pack, 100 packs/pallet (moisture-proof packaging)

– Frosted Surface Advantage: 30% higher anti-slip performance than smooth sheets, preventing PCB displacement; micro-matte texture avoids scratch marks on PCB surfaces, reducing defect rate by 15%.

– Dual Protection Options: Standard version for basic scratch prevention; Antistatic PP Sheet variant for ESD-sensitive PCBs, compatible with 5G and automotive PCB production.

– Cost-Effective Durability: Reusable 50+ times (vs. 20 times for low-quality PP sheets), lowering per-unit protection cost by 40%.

– Wide Compatibility: Suitable for rigid PCBs, FPCs, and IC载板; works with PCB Separator Sheet equipment and storage racks.

– Easy Post-Processing: Accepts printing (for batch marking) and glue application (for special bonding needs) after surface treatment.

1. Preparation: Clean PCBs with a Nylon brush to remove dust; ensure sheets are dry (use Gel timer to monitor workshop humidity ≤60%).

2. Separation: Place one frosted sheet between two PCBs, ensuring full coverage of the PCB surface (align edges to avoid offset).

3. Stacking: Stack up to 50 PCB-sheet pairs per layer; use PP Sponge Roller to press lightly for tight fit.

4. Storage/Transport: Store stacked PCBs in moisture-proof warehouses; for long-distance shipping, wrap pallets with waterproof film.

5. Reuse: After use, wipe sheets with a clean cloth; discard if surface is worn or contaminated.

• PCB Production Lines: Separate PCBs after etching/plating to avoid scratch defects, matching the inspection process of CMI165 Surface Cu Thickness Tester.

• FPC Storage: Protect flexible circuits from creases and static, ideal for consumer electronics manufacturers.

• Automotive PCB Transport: Withstand vibration during shipping, ensuring high-reliability PCBs (e.g., ADAS modules) arrive intact.

• Electronics Assembly: Separate semi-finished products with components soldered, preventing pin damage.
