Frosted PCB Separator Sheet

Frosted PCB Separator Sheet is the most popular cost-effective Polypropylene (PP) solution for PCB/FPC scratch protection during storage and transportation. Its frosted surface boosts anti-slip performance, with optional Antistatic PP Sheet to meet ESD requirements. Ranging from 0.35-2mm thickness (0.5mm as standard), it supports full size customization. Paired with our Nylon brush and PVA Sponge Roller, it’s a core accessory for PCB quality control lines.

As the top-choice separator sheet in PCB factories, Welltronics Green Frosted PCB Separator Sheet solves the critical issue of surface scratches from stacked PCBs. The classic green color aligns with PCB workshop management standards, enabling quick identification and classification. Made of high-purity PP, it balances rigidity and flexibility—thin enough to save storage space, durable enough for repeated use. Its frosted micro-texture creates friction to avoid PCB slippage, while smooth edges (free round corners optional) prevent edge damage. It integrates seamlessly with production workflows, complementing tools like CMI500 Hole Cu Thickness Tester and PCB Separator Sheet equipment for automated lines.

– Green + Frosted Dual Advantage: Classic green for easy workshop classification; 30% higher anti-slip performance than smooth sheets, cutting PCB scratch defect rate by 18%.

– Flexible Protection Options: Standard green frosted sheet for general PCBs; Antistatic PP sheet version for ESD-sensitive 5G/automotive PCBs, compatible with CMI700 Cu Thickness Tester workflows.

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

– Easy Post-Processing: Accepts printing (batch logos) and glue application after surface treatment, meeting customization needs.

– Wide Compatibility: Fits rigid PCBs, FPCs, and IC carrier board; works with manual and automated stacking.

1. Preparation: Clean PCBs with Nylon Brush to remove dust; use Gel timer to ensure workshop humidity ≤60% (prevents moisture damage).

2. Separation: Place one frosted sheet between two PCBs, aligning edges to cover the entire surface.

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

4. Storage/Transport: Store in a dry warehouse; for shipping, wrap pallets with waterproof film to protect sheets.

5. Reuse: After use, wipe sheets with PVA Sponge Roller ; discard if surface is worn or contaminated.

• Mass PCB Production Lines: Separate PCBs after etching/plating, matching CMI165 Surface Cu Thickness Tester inspection—green color ensures quick sorting, reducing mixing errors.

• Consumer Electronics FPC Storage: Prevent creases and scratches for smartphone/wearable flexible circuits, reusable with Nylon Brush cleaning.

• Automotive PCB Transport: Withstand vibration during long-distance shipping, ensuring ADAS module PCBs arrive intact, paired with PP Sponge Roller for stable stacking.

• Small-Batch PCB Workshops: Custom size options for prototype PCBs, green frosted surface easy to mark, reducing material waste by 25%.

A1: Green aligns with global PCB workshop management standards—easy to distinguish from PCBs (usually brown/green) and reduces sorting errors, improving workflow efficiency.

A1: Yes—5 free standard samples (0.5mm, 18″”×22″”); custom size samples take 3 days, sample fee refundable on bulk orders.

A2: Standard orders (≤50,000pcs): 1 week; bulk orders (≥100,000pcs): 2 weeks, with partial shipment available.
