Embodiment
The embodiment of the present invention is described in detail below in conjunction with accompanying drawing.It should be appreciated that this place is retouched
The embodiment stated is merely to illustrate and explain the present invention, and is not intended to limit the invention.
In the present invention, in the case where not making opposite explanation, " inside and outside, upper and lower " etc. is included in the noun of locality in term
Only represent orientation of the term under normal service condition, or be skilled artisan understands that be commonly called as, and be not construed as pair
The limitation of the term.
Referring to Fig. 1 and Fig. 2, the present invention provides a kind of PCBA board steel mesh printing opacity method of testing, including：
Step 1, installation PCBA board steel mesh printing opacity testing jig；
Step 2, the top that PCBA board steel mesh 4 to be tested is lain in a horizontal plane in PCBA board steel mesh printing opacity testing jig；
Step 3, irradiation light 2 is opened from bottom irradiation PCBA board steel mesh 4；
Step 4, manually adjust via regions of the magnifying glass 3 to PCBA board steel mesh 4 and observe irradiation light light whether
It can pass through.
Pass through above-mentioned technical proposal, PCBA board steel mesh printing opacity testing jig is first installed, then by PCBA board steel mesh to be tested
Lie in a horizontal plane in the top of PCBA board steel mesh printing opacity testing jig；Then, open irradiation light and irradiate PCBA board steel mesh from bottom, finally
Whether manually adjust via regions of the magnifying glass to PCBA board steel mesh and observe the light of irradiation light can pass through.Thus may be used
See, the PCBA board steel mesh printing opacity method of testing step is simple, easy to operate, rapidly and accurately PCBA board steel mesh can be carried out saturating
Optical tests, it ensure that PCBA board printing quality.
PCBA board steel mesh printing opacity testing jig in step 1 includes shape framework 1, irradiation light 2 and magnifying glass 3；Wherein, rectangle frame
The top end face of frame 1 and one of side are set to be open, and its excess-three side and bottom face closure are set；Irradiation light 2 is set
Irradiated in the inside of rectangular frame 1 and towards top is open, PCBA board steel mesh 4 can be erected in the opening of top；Magnifying glass 3 passes through
