Ingxenye engabizi kakhulu elahlekile ingalibazisa ukuthunyelwa njenge-IC ebizayo elahlekile uma idingeka kuwo wonke amabhodi. Ukulungiswa kabusha kungandisa nezindleko lapho izingxenye kunzima ukuzisusa, izinyathelo zonyawo zibucayi noma izingxenye ezithathelwa indawo zilinganiselwe.

Indlela engcono kakhulu yokunciphisa le ngozi ukuhlonza izingxenye ezibalulekile kusenesikhathi. Izingxenye ezihlukile, ezibizayo, ezinde, okunzima ukuzilungisa kabusha noma ezidingekayo ebhodini ngalinye kufanele zihlolwe ngaphambi kokuba umugqa uhlelwe. Uma ikhasimende livumela ukwakhiwa okungaphelele, leso sinqumo kufanele siqinisekiswe ngaphambi kokuba kuqale ukukhiqiza.

Izibonelo Zezingozi Zezindleko

1. Ingxenye engasebenzi engekho: Ulayini we-SMT ungase ume noma amabhodi angase abanjwe engaphelele.
2. Kunikezwe iphakheji engalungile: imvume yokufaka esikhundleni noma izingxenye ezintsha ziyadingeka.
3. Ukungakhuli ngokwanele: Ukusethwa kwe-feeder noma ukuphinda kusetshenziswe kungadla zonke izingxenye ezitholakalayo.
4. Imfuneko yokuhlolwa sekwephuzile: uhlelo lokuhlola kanye nokulethwa kumele lushintshwe ngemva kwesilinganiso.
5. I-polarity engacacile: ukukhiqizwa kungase kumiswe okwesikhashana ukuze kuqinisekiswe ubunjiniyela.

Ukuze ulawule lezi zingozi, thumela ikhithi ephelele, unikeze ngokweqile, uphawule izinto ezizosetshenziswa esikhundleni sazo bese uqinisekisa izidingo zokuhlola ngaphambi kokukhishwa kwenhlangano.

Ubuningi, Isikhathi Sokuhola kanye Nesigaba Sokukhiqiza

Izindleko zeyunithi ziyashintsha ngobuningi ngoba isikhathi sokusetha, izindleko ze-stencil, ukubuyekezwa kokuhlela kanye nobunjiniyela kusatshalaliswa emabhodini amaningi. Iphrothokholi ingaba nezindleko zeyunithi eziphezulu ngoba umzamo wokusetha ufana nokwakhiwa okukhulu. I-oda lokukhiqiza linganciphisa izindleko zeyunithi lapho amafayela, inqubo yekhithi kanye nezidingo zokuhlola zizinzile.

Isikhathi sokulethwa singathinta nezindleko. Ukwakhiwa okuphuthumayo kungadinga ukubuyekezwa kwamafayela okusheshayo, ukuhlela okukhethekile noma ukuthunyelwa okusheshayo. Uma ikhithi ingaphelele, ukuhlanganiswa okusheshayo kungase kungenzeki ngisho noma ifektri inamandla. Ekwakhiweni okubucayi ngesikhathi, ikhasimende kufanele lithumele amafayela edijithali kuqala bese lithumela ikhithi enamadokhumenti okupakisha acacile.

Ukuze uthole ushintsho ekukhiqizeni, bheka i-prototype kuya ekuhlanganisweni kwe-PCB yokukhiqiza.
