4L, Black Soldermask
This 4-layer black soldermask is designed for printed circuit boards (PCBs) requiring high durability and protection against environmental factors. The board uses ITEQ TG180 as its base material, known for its thermal stability and reliability in high-demand electronic applications. With a thickness of 1.60±0.15mm, it meets standard industry tolerances for 4-layer PCBs, ensuring compatibility with most assembly processes.
The soldermask features a minimum hole size of 0.20mm (8mil) and a minimum trace width of 0.089mm (3.5mil), which are critical for precision in dense circuit designs. Black soldermask is often chosen for its aesthetic appeal in consumer electronics, as well as its ability to reduce light reflection in optical applications. The material is typically UV-cured to provide resistance to solvents, heat and mechanical stress.
This product is suited for manufacturers of consumer electronics, automotive systems and industrial equipment where reliable circuit performance is essential. The 4-layer configuration is common for mid-complexity PCBs, balancing cost and functionality. Buyers should confirm if the supplier provides design support or prototyping services for custom layouts.

Sourcing 4L Black Soldermask from Shenzhen Hemeixin Electronic Co., Ltd. - China Import Guide
Before placing an order, confirm the PCB’s design files and Gerber data are compatible with the supplier’s manufacturing capabilities. Verify if the supplier offers design rule checks (DRC) to identify potential issues like trace spacing or hole sizes that may violate their production limits. Request samples for prototype validation if producing a new design.
Discuss logistics options, as PCBs are typically shipped via air or sea freight depending on urgency. Standard Incoterms for electronics imports from China include FOB Shenzhen or CIF to your local port, with payment terms often negotiated as T/T (30% deposit, 70% before shipment). Confirm packaging standards, as PCBs are usually vacuum-sealed and shipped in anti-static bags to prevent damage.
For quality assurance, require pre-shipment inspection reports that include visual checks for soldermask defects, dimensional accuracy and electrical continuity tests. For critical applications, arrange third-party testing for parameters like dielectric strength, thermal cycling and solderability. Documentation should also include RoHS compliance certificates if the PCBs are intended for markets with environmental restrictions.
