Embodiment Construction
[0012] The present invention will be further explained below in conjunction with the accompanying drawings.
[0013] like figure 1 As shown, a printing head of a packing printing machine for HTCC shell through-hole filling includes a scraper clamp 2 and a printing scraper 1 clamped by the scraper clamp 2 . The printing scraper 1 has an inverted triangular bottom, grooves are slotted on one slope of the inverted triangular bottom along the direction perpendicular to the movement of the printing head, and the starting point of the width of the grooves is located at the apex of the inverted triangle. The material of the scraping fixture 2 is silica gel, and the width b along the moving direction of the printing head is 5-9 mm. The inclination angle of the inclined surface on the side without grooves at the bottom of the inverted triangle is α1, which is 20°-40°, and the inclined angle of the inclined surface on the side with grooves at the bottom of the inverted triangle is α2, ...

The invention discloses a printing head of a filling printing machine used for filling through holes of HTCC tube shells, which includes a scraper clamp and a printing scraper clamped by the scraper fixture, the printing scraper has an inverted triangular bottom end, A groove is formed on one slope at the bottom end of the inverted triangle along the direction perpendicular to the movement of the printing head, and the starting point of the width of the groove is located at the apex of the inverted triangle. By using the printing head of the printing machine of the present invention, the effect of printing once to achieve two times of filling printing is realized, and the situation that the paste in the through hole is not full after one printing is improved, thereby avoiding the increase of the resistance of the through hole circuit caused by the filling being not full, and the through hole The problem of open circuit resistance of the circuit greatly improves the production efficiency and improves the production yield.
Description
technical field [0001] The invention relates to a printing head of a filling printing machine used for filling through holes of HTCC shells. Background technique [0002] In order to ensure the interconnection between layers, multi-layer co-fired ceramic shells often use green ceramic through-hole filler printing technology to ensure interlayer circuit communication. With the miniaturization, thinning and light weight of ceramic shells, the wiring density increases. As well as the improvement of electrical performance requirements, the through-hole filler printing process is one of the key processes in the production of ceramic shells. The quality of green ceramic through-hole filler printing often directly determines the yield of ceramic shell production. [0003] In the process of implementing the present invention, it is found that in the existing filling technology for shell through-holes, the paste surface printed once by the filler is in a concave state, and a second p...
