1. Mzere wa chizindikiro womwe uyenera kukhala wolepheretsa uyenera kukhazikitsidwa motsatira m’lifupi mwake ndi kutalika kwa mzere wowerengedwa ndi stack. Mwachitsanzo, wailesi pafupipafupi chizindikiro (yachibadwa 50R ulamuliro), zofunika single-kutha 50R, kusiyana 90R, kusiyana 100R ndi mizere chizindikiro chizindikiro, yeniyeni mzere m’lifupi ndi mzere katayanitsidwe akhoza kuwerengedwa ndi stacking (chithunzi pansipa).

2. Kupanga mzere m’lifupi ndi katayanidwe ka mizere ziyenera kuganizira luso la kupanga kwa omwe asankhidwa PCB fakitale yopanga. Ngati mzere m’lifupi ndi katayanitsidwe mzere waikidwa kupyola luso ndondomeko ya kugwirizana PCB wopanga pa kamangidwe, zosafunika ndalama kupanga ayenera kuonjezedwa, ndipo kamangidwe sangathe kupangidwa. Nthawi zambiri, m’lifupi mwa mizere ndi katalikirana ka mizere amayendetsedwa mpaka 6/6mil nthawi zonse, ndipo pobowo ndi 12mil (0.3mm). Kwenikweni, opitilira 80% opanga PCB amatha kupanga, ndipo mtengo wake ndi wotsika kwambiri. M’lifupi mwake ndi katalikirana ka mzere umayendetsedwa mpaka 4/4mil, ndipo pobowo ndi 8mil (0.2mm). Kwenikweni, oposa 70% opanga PCB amatha kupanga, koma mtengo wake ndi wokwera mtengo kwambiri kuposa woyamba, osati wokwera mtengo kwambiri. M’lifupi mwake ndi kutalika kwa mizere kumayendetsedwa mpaka 3.5/3.5mil, ndipo pobowo ndi 8mil (0.2mm). Panthawiyi, ena opanga PCB sangathe kutulutsa, ndipo mtengo udzakhala wokwera mtengo. The osachepera mzere m’lifupi ndi mizere katayanitsidwe amalamulidwa kuti 2/2mil, ndi kudzera dzenje ndi 4mil (0.1mm, pa nthawi ino, ndi zambiri HDI akhungu kukwiriridwa kudzera kapangidwe, ndi laser vias chofunika). Panthawi imeneyi, opanga PCB ambiri sangathe kuzipanga, ndipo mtengo ndi wokwera mtengo kwambiri. M’lifupi mwa mzere ndi katalikidwe ka mizere pano akutanthauza kukula pakati pa zinthu monga mzere-to-bowo, mzere-mpaka-mzere, mzere-to-pad, mzere-kudutsa, ndi dzenje-to-disk poika malamulo.

3. Khazikitsani malamulo kuti muganizire za botolo la mapangidwe mu fayilo yojambula. Ngati pali chip 1mm BGA, kuya kwa pini kumakhala kozama, mzere umodzi wokha umafunika pakati pa mizere iwiri ya zikhomo, zomwe zingathe kukhazikitsidwa ku 6/6 mil, kuya kwa pini kumakhala kozama, ndipo mizere iwiri ya pini imafunika. Mzere wa chizindikiro umayikidwa ku 4/4mil; pali chipangizo cha 0.65mm BGA, chomwe nthawi zambiri chimakhala 4/4mil; pali 0.5mm BGA Chip, ambiri mzere m’lifupi ndi katayanitsidwe mzere ayenera kukhala 3.5/3.5mil; pali 0.4mm BGA Chips zambiri amafuna HDI kapangidwe. Nthawi zambiri, pakupanga botolo, mutha kukhazikitsa malamulo amderali (onani kumapeto kwa nkhaniyo [AD mapulogalamu kuti akhazikitse ROOM, ALLEGRO mapulogalamu kukhazikitsa malamulo achigawo]), ikani mzere wam’derali m’lifupi ndi malo otalikirana mpaka pang’ono, ndikuyika malamulo a mbali zina za PCB kukhala zazikulu kupanga. Sinthani mlingo woyenera wa PCB opangidwa.

4. Iyenera kukhazikitsidwa molingana ndi kachulukidwe ka mapangidwe a PCB. Kachulukidwe ndi kakang’ono ndipo bolodi ndi lotayirira. M’lifupi mwa mizere ndi katalikirana ka mzere ukhoza kukhazikitsidwa kukhala wokulirapo, ndipo mosinthanitsa. Chizoloŵezicho chikhoza kukhazikitsidwa motsatira njira zotsatirazi:

1) 8 / 8mil, 12mil (0.3mm) chifukwa kudzera dzenje.

2) 6 / 6mil, 12mil (0.3mm) chifukwa kudzera dzenje.

3) 4 / 4mil, 8mil (0.2mm) chifukwa kudzera dzenje.

4) 3.5 / 3.5mil, 8mil (0.2mm) chifukwa kudzera dzenje.

5) 3.5 / 3.5mil, 4mil ya kudzera pa bowo (0.1mm, pobowola laser).

6) 2 / 2mil, 4mil ya kudzera pa bowo (0.1mm, pobowola laser).
