the hole wall metallization process adopts a raw ceramic chip framing mode, namely the raw ceramic chip is pasted on a metal frame by using a special adhesive tape, so that the deformation of the raw ceramic chip in the whole process flow is reduced; the upper surface of the metal frame and the upper surface of the green ceramic chip are on the same plane, and the lower surface of the metal frame and the lower surface of the green ceramic chip are not on the same plane due to the difference of the thickness of the metal frame and the thickness of the green ceramic chip; in the hole wall metallization process, when the scraper applies pressure to the upper surface of the green ceramic sheet for missing printing, the lower surface of the green ceramic sheet has no supporting plane, so that the green ceramic sheet deforms, the position of the graph of the green ceramic sheet changes, the graph which is missed to the green ceramic sheet from the screen printing plate and the graph position of the green ceramic sheet are deviated, the position precision is low, and the final yield is reduced.
The prior art for metalizing the framed hole wall of the green ceramic chip comprises the following steps: the thickness difference between the green ceramic chip and the metal frame is realized by adjusting the mask plates with different thicknesses, and the stainless steel material die with the mask plate of 0.2mm-0.4mm is used for stamping, so that the position precision of the holes on the mask plate is ensured and can reach 5 microns; however, the precision of the thickness of the mask plate is 0.1mm, and the precision of the thickness of the green ceramic chip is 0.01mm, so that the method adopting the mask plates with different thicknesses has the following problems: one is as follows: the thickness precision of the mask plate is lower than that of the green ceramic chip, the lower surface of the metal frame and the lower surface of the green ceramic chip cannot be in the same plane, and the green ceramic chip still deforms in the hole wall metallization process, so that the precision of the hole wall metallization position is reduced; and the second step is as follows: the height difference between the lower surface of the metal frame and the lower surface of the green ceramic chip cannot be accurately quantified, and the degree of whether the two surfaces are in the same plane can be sensed only by hand feeling, so that the efficiency and the reliability are reduced. From the above problem, we can conclude that: the process has the problems of low position precision, low efficiency and low reliability.
