7. Matsi na Kiss

When the multilayer board is pressed, when the plates in each Opening are placed and positioned, it begins to heat up and lift up from the bottom hot plate with a powerful hydraulic top column (Ram) to press the loose material in each Opening for bonding. A wannan lokacin haɗe da fim ɗin (Prepreg) ya fara yin laushi a hankali har ma da gudana, don haka matsa lamba da aka yi amfani da shi don extrusion na sama ba zai iya zama babba ba, don kauce wa zamewar faranti ko manne da yawa.

Tun 1986, lokacin da bukatar hudu da shida laminates ya karu, hanyar laminating multilaminates ya canza da yawa. In the early stage, only one shipment plate was arranged on the process plate to be pressed. This one-to-one arrangement has been broken in the new law, which can be changed into a pair of two, or a pair of four, or even more rows of plates to be pressed together according to its size. Na biyu shine soke kowane nau’in kayan sako-sako (kamar takardar ciki, fim, takardar waje ɗaya, da sauransu) na tip ɗin daidaitawa; The outer layer is changed to copper foil, and the “target” is pre-made on the inner layer plate, which is “swept” to get the target after pressing, and then the tool hole is drilled from the center, which can be set on the drilling machine for drilling. Dangane da allon allon shida ko takwas, ana iya yin fim ɗin kowane Layer na ciki da sanwici sannan a danna shi a babban zafin jiki.
