SPECIFICATION:
Name: Double-layer PCB
Material: FR4
Application: Test Instrument
Layers/plate thickness: 2L/1.6mm
Surface Treatment: HASL
Line width/line spacing: 4.5/4.5mil
Minimum aperture: 0.25mm
Two-sided PCB model, the foremost normally surface treatment is HASL. At constant time, OSP, gold plating, immersion gold, immersion silver, is equally applicable.
HASL- sensible appearance, simple to weld tin on the pad, easy welding, low price.
Double sided boards are wide used and relatively easy, each manufacturer can do, that the competition is usually on the price.

ENIG- stable quality, sometimes employed in the case of boding IC. For two sided board, using through hole within the middle connects two-sided traces, and there are 2 more processes than single aspect board, that is Electroless Copper and plating.
