Import 3.2mm, 20l Blind&Buried Vias Board — Buy in Bulk from Supplier in China

This 20-layer PCB from Shenzhen Hemeixin Electronics Co., Ltd. uses FR-4 TG170 as the base material with a board thickness of 3.2mm ± 0.3mm, designed for high-density interconnect applications. All copper layers are plated to 2OZ, and the board incorporates blind and buried vias with a minimum hole diameter of 0.50mm (19mil), supporting advanced routing requirements. Surface finishing is ENIG, ensuring reliable solderability and corrosion resistance for long-term performance.

The PCB features a minimum trace width and spacing of 0.20mm (8mil), enabling tight routing in compact designs. Panel dimensions are 106.63mm x 134.42mm with a 6up configuration arranged as 2x3, and the design includes 2-step blind vias (dr1-2, dr3-4) with a via diameter of 0.5mm (19mil). Testing is performed via flying probe to verify electrical continuity and isolation, a standard method for high-layer-count boards.

This board is suited for applications requiring high-layer density, such as telecommunications equipment, industrial control systems, and advanced computing hardware. Buyers typically source these for prototypes or volume production, with lead times of 10 working days for expedited orders or 15-20 working days for standard delivery. The ENIG finish and FR-4 TG170 material are standard choices for reliability in demanding thermal environments.
