Pad Test

A pad is a knot of a wire-line connecting parts on the PCB board.  We offer different heads and sizes to test shrinking pads.
 
Generally if the pad is smaller than 15mil, we will use the crown head to make contact with the smaller pad. Sharp tips will always miss the
target.If you are uncertain whether the fixture is stable and high precision; multi-point head is recommended. If the pad is bigger than 20mil, we
can use an aggressive head to puncture the flux covering the pad.
Different test situations require different solutions, We must keep a balance between tested parts and probes to make the FPY higher and to
give the probe a longer life.

Pad size:8-12mil, I064 head is recommended.

Pad size:over 24mil , A(cone),WW(sharp dagger) is recommended
