ambiri PCB okonda mapangidwe, makamaka oyamba kumene, samamvetsetsa bwino magawo osiyanasiyana pamapangidwe a PCB. Sakudziwa ntchito yake ndi kugwiritsa ntchito. Nali kufotokozera mwadongosolo kwa aliyense:

1. Makina osanjikiza, monga momwe dzinalo limatanthawuzira, ndi mawonekedwe a bolodi yonse ya PCB yopangira makina. M’malo mwake, tikamalankhula za wosanjikiza wamakina, tikutanthauza mawonekedwe onse a bolodi la PCB. Ikhoza kugwiritsidwanso ntchito kukhazikitsa miyeso ya bolodi la dera, zizindikiro za deta, zizindikiro zogwirizanitsa, malangizo a msonkhano ndi zina zamakina. Zambirizi zimasiyanasiyana malinga ndi zofunikira za kampani yojambula kapena wopanga PCB. Kuphatikiza apo, makina osanjikiza amatha kuwonjezeredwa ku zigawo zina kuti atulutse ndikuwonetsa pamodzi.

2. Sungani wosanjikiza (wosanjikiza woletsedwa), womwe umagwiritsidwa ntchito kufotokozera malo omwe zigawo ndi mawaya amatha kuikidwa bwino pa bolodi la dera. Jambulani malo otsekedwa pamzerewu ngati malo abwino olowera. Zosanjikiza zokha ndi njira sizingatheke kunja kwa derali. Wosanjikiza woletsedwa wa wiring amatanthauzira malire tikayika mawonekedwe amagetsi amkuwa. Ndiko kunena kuti, titatha kufotokozera mzere woletsedwa wa wiring, m’tsogolomu, mawaya okhala ndi magetsi sangathe kupitirira chingwe choletsedwa. Pamalire a wosanjikiza, nthawi zambiri pamakhala chizoloŵezi chogwiritsa ntchito Keepout layer ngati makina osanjikiza. Njirayi ndi yolakwika, choncho tikulimbikitsidwa kuti mupange kusiyana, apo ayi fakitale ya bolodi iyenera kusintha zizindikiro zanu nthawi iliyonse yomwe mumapanga.

3. Chingwe cha chizindikiro: Chizindikiro cha chizindikiro chimagwiritsidwa ntchito makamaka kukonza mawaya pa bolodi la dera. Kuphatikiza Pamwamba (pamwamba), Pansi (pansi) ndi 30 MidLayer (pakati). Zigawo Zapamwamba ndi Pansi zimayika zida, ndipo zigawo zamkati zimayendetsedwa.

4. Top paste and Bottom paste are the top and bottom pad stencil layers, which are the same size as the pads. This is mainly because we can use these two layers to make the stencil when we do SMT. Just dug a hole the size of a pad on the net, and then we cover the stencil on the PCB board, and apply the solder paste evenly with a brush with solder paste, as shown in Figure 2-1.

5. Top Solder ndi Pansi Solder Ichi ndi solder chigoba kuteteza wobiriwira mafuta kuti asaphimbidwe. Nthawi zambiri timati “tsegulani zenera”. Mkuwa wamba kapena waya wophimbidwa ndi mafuta obiriwira mwachisawawa. Ngati tigwiritsa ntchito chigoba cha solder moyenerera Ngati chikugwiritsidwa ntchito, chidzalepheretsa mafuta obiriwira kuti asaphimbe ndikuwulula mkuwa. Kusiyanitsa pakati pa ziwirizi kumawoneka pachithunzi chotsatirachi:

6. Mzere wa ndege wamkati (mphamvu zamkati / pansi): Mtundu uwu wamtunduwu umangogwiritsidwa ntchito pa matabwa a multilayer, makamaka omwe amagwiritsidwa ntchito pokonza mizere yamagetsi ndi mizere yapansi. Timatcha matabwa a magawo awiri, matabwa a zigawo zinayi, ndi matabwa asanu ndi limodzi. Chiwerengero cha zigawo za chizindikiro ndi zigawo zamkati za mphamvu / pansi.

7. Silkscreen layer: Silkscreen layer imagwiritsidwa ntchito kwambiri poyika zidziwitso zosindikizidwa, monga zolemba zamagulu ndi zilembo, zilembo zosiyanasiyana, ndi zina zotero. Altium imapereka zigawo ziwiri za skrini ya silika, Top Overlay ndi Bottom Overlay, kuyika mafayilo apamwamba a silk screen ndi pansi silika chophimba owona motero.

8. Mipikisano wosanjikiza (Mipikisano wosanjikiza): The ziyangoyango ndi vias olowerera pa bolodi dera ayenera kudutsa gulu lonse dera ndi kukhazikitsa kugwirizana magetsi ndi osiyana conductive chitsanzo zigawo. Choncho, dongosolo lakhazikitsa abstract layer-multi-layer . Kawirikawiri, mapepala ndi vias ayenera kukonzedwa pazigawo zingapo. Ngati wosanjikiza uwu wazimitsidwa, mapepala ndi vias sangathe kuwonetsedwa.

9. Drill Drawing (kubowola wosanjikiza): Kubowola wosanjikiza kumapereka chidziwitso pakubowola panthawi yopanga bolodi yozungulira (monga mapepala, vias ayenera kubowoledwa). Altium imapereka zigawo ziwiri zobowola: Drill gridi ndi Drill zojambula.
