[0012] The examples will now illustrate the present invention in further detail.
[0013] A method for producing a multi-layer board outer layer windowed copper skin lamination and selective PTH, comprising the following steps:
[0014] 1) Drill holes with the same diameter at the same position of the copper skin and the underlying product, and use the jig sleeve to locate the position for the fitting operation;
[0015] 2) After the copper skin and the underlying product are laminated, carry out two drills, and print a layer of peelable glue by screen printing in the place where the surface of the product needs to be shielded;
[0016] 3) Bake the product and cure the peelable glue, and then do the PTH operation.
[0017] After the PTH operation, the peelable glue does not float up, and it covers the exposed circuit perfectly.
[0018] In the step 1), the bottom product is first positioned and fixed on the fixture through the fixture cover, and then the copper sheet is cove...
