M’mapangidwe a PCB, abwenzi ambiri sadziwa zokwanira za zigawo za PCB, makamaka woyambira, udindo wa gawo lililonse sadziwika. Pakadali pano, tiyeni tiwone zojambula zojambula za AlTIumDesigner, pali kusiyana kotani pagawo lililonse.

1. Chizindikiro chachizindikiro

Mzere wosanjikiza wagawidwa mu TopLayer (TopLayer) ndi BottomLayer (BottomLayer), womwe umalumikizana ndi magetsi ndipo umatha kuyika zida ndi zingwe.

2. Mawotchi wosanjikiza

Mawotchi ndiye tanthauzo la mawonekedwe a gulu lonse la PCB. Kutsindika kwa “Mawotchi” kumatanthauza kuti ilibe magetsi, kotero itha kugwiritsidwa ntchito moyenera pojambula mawonekedwe, kujambula kukula kwa Mawotchi, kuyika zolemba, ndi zina zotero, osadandaula za zosintha zamagetsi zama board. Pazithunzi zosanjikiza za 16 zimatha kusankhidwa.

3. Screen yosindikiza wosanjikiza

Pamwamba Pamwamba ndi Kuphimba Pansi amagwiritsidwa ntchito kutanthauzira mawonekedwe osindikiza apamwamba ndi Pansi. Ndi zilembo zosindikizidwa Pamwamba pazitsulo zosakanikirana ndi solder, monga dzina lazinthu, chizindikiro chamagulu, pini yamagulu, ndi kukopera, kuti athandizire kuwotcherera dera ndikuwona zolakwika.

4. Chosanjikiza chitini

Solder Paste wosanjikiza imaphatikizira gawo la Pamwamba Pamwamba ndi Gawo Loyambira Pansi, lomwe limatanthawuza pamwamba Paste pad yomwe titha kuwona kunja, ndiye kuti, gawo lomwe limafunikira kukutidwa ndi solder Matani musanadule. Chifukwa chake kusanjikaku ndikothandiza pakukhazikika kwa mpweya wa padyo ndikupanga mauna achitsulo.

5. Welding kukana wosanjikiza

Solder wosanjikiza amatchulidwanso kuti “kutseka,” kuphatikiza TopSolder ndi BottomSolder, yomwe imagwira ntchito yotsutsana ndi phala la solder ndipo amatanthauza wosanjikiza kuphimba mafuta obiriwira. Mzerewo ndi wosungunuka kwaulere kuti uteteze kufupika kwakanthawi kosungunuka kowonjezera pamalumikizidwe oyandikana nawo pakuwotcherera. Chosanjikiza cha solder chimakwirira waya wamafilimu ndikulepheretsa kanema wamkuwa kuti asatengeke msanga mlengalenga, koma malowo adayikidwa pambali pa cholumikizira cha solder ndipo sichiphimba cholumikizira cha solder.

Kuphimba kophatikizira kwamkuwa kapena kachingwe ndiye mafuta obiriwira osavomerezeka, ngati ifenso tikugwiritsa ntchito mankhwala osanjikiza, titha kuteteza mafuta obiriwira, kuwulula mkuwa.

6. Pobowola wosanjikiza

Mzere wosanjikiza umakhala ndi DrillGride ndi DrillDrawing. Chojambulira chimagwiritsidwa ntchito popereka chidziwitso cha mabowo obowolera munjira yopangira bolodi (monga mapadi, omwe amafunika kubowolezedwa kudzera m’mabowo).

7, kuletsa zingwe zosanjikiza zoletsa zingwe zosanjikiza (KeepOutLayer) zomwe zimagwiritsidwa ntchito kutanthauzira malire a zingwe, pambuyo pofotokozera choletsa cholumikizira, mtsogolo mtsogolo, ndi mawonekedwe amagetsi sangadutse malire a choletsa cholumikizira.

8. Mipikisano wosanjikiza

Ma pads ndi mabowo olowera pa bolodi amayenera kudutsa bolodi lonselo ndikukhazikitsa kulumikizana kwamagetsi ndi magawo osiyanasiyana owoneka bwino, chifukwa chake dongosololi limakhazikitsa wosanjikiza – wosanjikiza. Nthawi zambiri, ma pads ndi mabowo amayikidwa pamitundu ingapo, ndipo ngati gawo ili litatsekedwa, ma pads ndi mabowo sadzawonetsedwa.
