A cikin ƙirar PCB da samar da taro na PCB na ƙarshe, Majalisar PCB shima abu ne mai mahimmanci, wanda ba wai kawai ya haɗa da daidaiton ƙimar hukumar PCB ba, amma kuma yana shafar farashin samar da PCB. Yadda za a tabbatar da ingancin hukumar PCB, taro mai ma’ana da inganci, don adana albarkatun ƙasa, kamfanin samarwa yana ba da babbar mahimmanci don warware matsala.

1. Yanayin haɗin gwiwa

Akwai hanyoyin haɗi guda biyu na PCB, ɗayan shine V-yanke, ɗayan shine haɗin ramin hatimi. V-yanke gabaɗaya ya dace da PCB tare da siffa mai kusurwa huɗu, wanda ke da alaƙa mai kyau bayan rabuwa da ƙarancin farashin sarrafawa, don haka ana ba da shawarar yin amfani da shi da farko. Ramin hatimi gabaɗaya ya dace da haɗuwa da nau’in farantin da ba daidai ba, alal misali, tsarin firam ɗin MID “L” galibi yana ɗaukar hanyar haɗin ramin hatimi don tara farantin.

2. Yawan tarin:

Dole ne a kirga girman dukkan allon gwargwadon girman allon PCB guda. Girman allon gaba ɗaya bai wuce matsakaicin girman PCB ba (tsawon allon PCB bai wuce 250mm ba). Da yawa allon zai shafi daidaiton matsayin hukumar da daidaiton guntu. Gabaɗaya, babban kwamitin ajin MID allon 2 ne, kuma ƙaramin allon allo da allon LCD bai wuce allon 6 ba. An ƙaddara ƙaramin kwamitin yanki na musamman gwargwadon takamaiman yanayi.

3, buƙatun mashaya mahaɗin ramin hatimi

A cikin Mosaic na PCB, adadin sandunan haɗi yakamata su dace, gabaɗaya sandunan haɗin gwiwa 2-3, don ƙarfin PCB ɗin zai iya cika buƙatun tsarin samarwa, kuma kar a karye cikin sauƙi. Lokacin da aka ƙera mashaya mahaɗin, gabaɗaya ana buƙatar tsara tsayin 4-5mm, ramin ramin da ba ƙarfe ba, girman gabaɗaya 0.3mm-0.5mm, tazara tsakanin ramukan shine 0.8-1.2mm;

4. Hanyar aiwatarwa

Lokacin da jirgi ya yi yawa, sararin saman allon yana iyakance, buƙatar ƙara girman tsari, ana amfani dashi don gefen watsawa na hukumar PCT na SMT, gabaɗaya 3-5mm. Gabaɗaya, ana ƙara rami na sakawa zuwa kowane kusurwoyi huɗu na gefen tsari, kuma ana ƙara madaidaitan wuraren sakawa zuwa kusurwoyi uku don ƙarfafa matsayin injin.
