For surface of insulating layer stress is reduced, the light energy working control when solidifying the ground floor dielectric ink is at 650～750mj/cm
2, make printing ink be in semi-cured state, make its pencil hardness between HB～1H, improved the adherence of silver-colored slurry cross-line and insulating barrier, eliminated silver-colored slurry and insulating barrier segregation phenomenon.
The UV light energy of second layer insulating barrier ink solidification is controlled at 700～800mj/cm
2Semi-cured state, the adhesion of reinforced insulation layer and silver slurry cross-line.
Silver slurry cross-line: adopt single face PCB silk-screen printing technique; Select to satisfy the silver-colored 170 order silk screens and the 40 μ m thickness films of starching the resistance requirement of cross-line and process printing screen plate; Make the silver slurry cross-line thickness of each printing keep consistent relatively, to keep product silver slurry cross-line resistance stability.
The UV light energy of ground floor silver slurry cross-line protective layer printing ink is controlled at 700～800mj/cm
2Semi-cured state, the adhesion of reinforced insulation layer and silver slurry cross-line.
One. U.S. ACHESON 976-SSHV (or Korea S sun NS-FSP04) the silver slurry of selecting low-resistivity for use has relatively low potential difference as the cross-line printing material to guarantee the circuit that cross-line connects;
Two. select for use the lower Shanghai of pencil hardness auspicious Le Tian village USR-11G-11 ultraviolet curing type welding resistance printing ink as insulating barrier printing ink between two conductive layers and silver slurry protective layer; And the light energy technological parameter of control ink solidification; Can guarantee insulating properties, accomplish that again insulating barrier and silver slurry cross-line have good adherence;
Three. cleaning fluid and the washing selecting to have degreasing and remove the Copper Foil oxidation are made up as silver-colored slurry cross-line printing pre-treating technology, and assurance silver is starched with the copper dish has stronger adherence, reduces the contact resistance of silver-colored slurry and copper dish.
Four. select for use hot curing resistance solder paste China ink as the last slurry of silver together cross-line protective layer printing ink; With better protection silver slurry cross-line; Improve the resistance to sudden heating of product, product is after process has the high temperature impact of plumbous hot air leveling, Reflow Soldering and wave-soldering, and silver slurry cross-line resistance has less rate of change.
Silver slurry cross-line printed wiring board of the present invention and plated-through hole double sided board compare: silver slurry cross-line production process of printed circuit board technology is through silk-screen printing technique; Cover the double-deck wiring board of formation on the copper sheet at single face; It is shorter than the life cycle of the product of plated-through hole double sided board explained hereafter; Efficient is high, more adapts to product and produces in enormous quantities; Most importantly do not use chemical plating process; The waste liquid that does not also just destroy environment produces, and has practiced thrift 50% copper raw material than plated-through hole double sided board, also greatly reduces product boring cost; The theory that meets cleaner production has positive meaning to environmental protection.
