Base Material: FR4-TG140 Surface Finish: HASL(Lead Free)
PCB Thickness: 1.6mm Solder Mask: Green
PCB Size: 25*76mm Silkscreen: White
Layer Count: 1/L Cu Thickness 35um(1oz)

What files are required to produce your PCBs:

1. PCB files (Gerber files).

2. The specific quantity.

3. PCB thickness,Material, Copper thickness, Surface finish,Solder mask color or any other requirements.

For PCB assembly, the more files are required as below:

1. Bom list (bill of material)

2. Centroid files (Pick & Place files)

3. Assembly drawings,

4. Extra requirement for assembly.

Surface Finish Process:


ENIG(Immersion Gold):

Immersion gold process deposits a nickel- gold coating with stable color, good brightness, flat coating and good solderability on the surface of the printed circuit, the cost is relatively more expensive.


HASL (Lead Free):

The flatness is insufficient, but HASL is low cost. Due to environmental protection requirements, there is a requirement for lead free.

HASL (Lead Free) process is widely used by customers.



Cover a layer of anti- oxidation protective film on the copper surface, the film thickness is uniform, the cost is low, but it is difficult to withstand multiple soldering.
