4.5 A / dm2. Edge illuminated, reddish in the middle for small current. Red, black, bright in the middle of the current) 16 Water 17 Polished Drying (drying the surface and the hole in the water) brush photosensitive line ink (90T screen box, if not a brush immediately brush board, brush clean and then re-drying brush) [Note: brush wire frame Try to wash with warm water about 50 ℃, the best bubble will be washed. To
Particles are attached to the hole. It is best to activate 2 times for the back copper preparation) [Note: drying 2 times] through the hole (the hole to remove excess activator to ensure that each hole are transparent) curing (100 ℃, 5 to 10 minutes, so that the carbon particles in the hole better adsorption) re-activation (30 ° C, current approx.
remove the drilling generated (5 minutes, degreasing, in addition to oxide, adjust the charge). If the hole is not transparent, use the smallest drill bit piercing. 60 ℃, for 5 minutes, the temperature is not enough, the time is long) Washing (washing is to remove the residual medicine) Drying (remove the residual moisture in the hole) [Note: 100 ℃] activation (2 to 4 minutes,
(Set the thickness of 2.0mm, drill from the board 1 ~ 1.5mm.). (Note: make the ink more clear, spray 2 times] 2 cutting board (20mm process edge) The maximum hole drilling, and then the largest. CCL must be double-sided adhesive in the drilling machine on the substrate) 4 grinding (polished with manual sanding) polishing (removal of surface oxide and oil
