Amabhodi wesifunda wePCB asetshenziswa kabanzi emikhiqizweni ehlukahlukene ye-elekthronikhi ezweni lanamuhla elithuthukiswa yi-Industrial. Ngokusho kwezimboni ezahlukahlukene, umbala, ukwakheka, usayizi, ungqimba, kanye nezinto ezibonakalayo zamabhodi wesifunda e-PCB ahlukile. Ngakho-ke, imininingwane ecacile iyadingeka ekwakhiweni kwamabhodi wesifunda ye-PCB, uma kungenjalo ukungaqondani kuthambekele kuye. Le ndatshana ifingqa amaphutha ayishumi aphezulu asuselwa ezinkingeni ezisezinhlokweni ze-PCB Circuit board.

1. Ukuchazwa kwezinga lokucubungula akucaci

Ibhodi elihlangene elilodwa lenzelwe ungqimba oluphezulu. Uma kungekho myalo wokukwenza ngaphambili nangemuva, kungaba nzima ukuthengisa ibhodi ngamadivayisi kulo.

2. Ibanga phakathi kwendawo enkulu ye-post foil kanye nohlaka lwangaphandle lusondele kakhulu

Ibanga phakathi kwe-foil ye-post-post enkulu kanye nohlaka lwangaphandle kufanele okungenani lube ngu-0.2mm, ngoba lapho kugaya i-foil yethusi, uma kukhunjulwa ku-foil yethusi, kubangele ukuthi umthengisi awele.

3. Sebenzisa amabhlogo we-filler ukudweba ama-pads

Amaphakethe wokudweba anamabhulokhi we-filler angadlula ukuhlolwa kwe-DRC lapho eklama amasekethe, kepha hhayi ukucubungula. Ngakho-ke, ama-pads anjalo awakwazi ukukhiqiza ngokuqondile idatha ye-solder mask. Lapho ukumelana kwe-solerd kusetshenziswa, indawo yebhulokhi ye-filler izombozwa ukumelana we-solder, okwenza ukuthi i-welding yedivayisi inzima.

4. Isendlalelo segesi sikagesi siyimbali yezimbali kanye nokuxhumeka

Ngoba yakhelwe njengokuhlinzekwa kwamandla ngendlela yama-pads, ungqimba lomhlabathi ubhekene nesithombe ebhodini langempela eliphrintiwe, futhi konke ukuxhumana kuyizintambo zodwa. Qaphela lapho udweba amasethi amaningi wokuhlinzekwa kwamandla noma imigqa yokuhlukaniswa komhlaba wonke, futhi ungashiyi izikhala ukwenza la maqembu amabili umjikelezo omfushane wokunikezwa kwamandla akwazi ukuvalwa.

5.

Amaphakethe we-SMD we-Complance Cover Pads aletha ukuphazamiseka ekuhlolweni okuku-On-off kwebhodi ephrintiwe kanye ne-Intenent Welding. Uma ukwakheka kwezinhlamvu kuncane kakhulu, kuzokwenza ukuphrinta kwesikrini kube nzima, futhi uma kukhulu kakhulu, izinhlamvu zizodlula, zenze kube nzima ukuhlukanisa.

6.Surface Mount Pads ama-pads amafushane kakhulu

Lokhu kungukuhlola okungaphezulu. Ngamadivayisi weNtaba emnyama kakhulu, ibanga phakathi kwezikhonkwane ezimbili lincane impela, futhi amaphakethe nawo mncane kakhulu. Lapho ufaka izikhonkwane zokuhlola, kufanele zinyakaze phezulu naphansi. Uma ukwakheka kwe-pad kufushane kakhulu, yize kungenjalo kuzothinta ukufakwa kwensiza, kepha kuzokwenza ukuthi izikhonkwane zokuhlola zihlukaniswe.

7. Ukuhlelwa kwe-single-side pad aperture

Amaphaphu ahlaselwe okukodwa ngokuvamile awakhiwa. Uma izimbobo ezibiwe zidinga ukumakwa, i-aperture kufanele yakhelwe njenge-zero. Uma inani lenzelwe, lapho-ke kukhiqizwa idatha yokumba, kuzovela izixhumanisi zemgodi kulesi sikhundla, futhi kuzovela izinkinga. Ama-pads ahlaselwe okukodwa njengezimbobo ezibiziwe kufanele zimakwe ngokukhethekile.

8. Pad sclap

Ngesikhathi senqubo yokumba, i-drill bit izophulwa ngenxa yokumba okuningi endaweni eyodwa, okuholela ekulimaleni komgodi. Lezi zimbobo ezimbili ebhodini le-multi-ungqimba ligqekeze, futhi ngemuva kokudonswa okubi, kuzovela njengepuleti yedwa, okuholela ekuchithekeni.

9. Kunamabhulokhi amaningi okugcwalisa ekwakhiweni noma emabhulokhi okugcwalisa agcwele imigqa emincane kakhulu

Idatha yokuqothula yezifo ilahlekile, futhi idatha yokuhlaziya ngezithombe ayiphelele. Ngoba ibhulokhi yokugcwalisa idonswa yinye ku-Fisha yokudweba idatha yokudweba, ngakho-ke inani lemininingwane yokudweba ekhanyayo ekhiqizwa likhulu impela, elikhulisa ubunzima bokucutshungulwa kwedatha.

10. Ukuhlukumezeka okuyisisekelo

Ukuxhumana okungenamsebenzi kwenziwe ngezendlalelo ezithile zehluzo. Bekungonangempela ibhodi elinobungqingili kepha lezendlalelo ezingaphezu kwezinhlanu zenzelwe, ezadalwa ukungaqondani. Ukwephulwa komklamo ojwayelekile. Isendlalelo sehluzo kufanele sigcinwe siqinile futhi sicace lapho siklama.
