从China供应商批发进口2 Layer Pcb — FOB条款

This 2-layer PCB from Elecrow Co., Ltd. in Shenzhen uses FR-4 material with a standard green solder mask, though red, yellow, blue, white, and black are also available. The board supports a maximum size of 45cm by 120cm and is offered in thicknesses of 0.6mm, 0.8mm, 1.0mm, 1.2mm, and 1.6mm, with a thickness tolerance of ±10% for 1.0mm boards. The outer copper layer is 1oz (35µm) with an inner layer of 17µm, and the surface finish options include standard HASL, lead-free HASL, and ENIG.

The PCB's technical capabilities include a minimum track and via spacing of 6mil (with a recommendation of >8mil), a minimum pad spacing of 8mil, and a minimum silkscreen text size of 32mil. Mechanical drilling can handle holes from 0.3mm to 6.35mm in diameter, with a finished hole tolerance of 0.1mm for plated holes and 0.05mm for unplated ones. The board outline tolerance is ±0.20mm, the aspect ratio is 8:1, and the photosensitive solder mask has a thickness of 15µm with a minimum width and clearance of 0.2mm.

These specifications make the PCB suitable for a variety of electronics projects, from consumer gadgets to industrial control systems. The minimum order quantity is 10 pieces, which is practical for prototyping and small-batch production. Buyers should confirm the exact pricing for their chosen surface finish, as ENIG incurs an additional charge, and verify the current lead time directly with Elecrow Co., Ltd. in Shenzhen before placing an order.
