Mubikorwa no gutunganya Automotive PCBA, ibibaho bimwe byakarere bigomba gutwarwa n'umuringa. Icyubahiro cy'umuringa kirashobora kugabanya ingaruka ziterwa no gutunganya ibicuruzwa bitunganya neza kugirango utezimbere ubushobozi bwo kurwanya no kugabanya ahantu hatangiriye. Ingaruka nziza irashobora gukoreshwa byuzuye muburyo bwo gutunganya. Ariko, hari ibintu byinshi byo kwitondera mugihe cyumuringa. Reka nkumenyeshe ibisobanuro birambuye kuri PCBA gutunganya inzira yumuringa.
一. Umuringa usuka
1. IGICE CYA PRETREATMENT: Mbere yo gusuka umuringa byemewe, harimo gusukura, guhagarika isuku, gusukurwa, gusukura nizindi ntambwe kugirango bibe umusingi wumuringa usuka umuringa.
2. Amashanyarazi adashobora gushushanya Ibyiza ni uko ubugari bwuzuye kandi bumwe bwa firime yumuringa bushobora kugenzurwa neza.
3. Gufotora muri imashini: Ubuso bwinama yumuzunguruko butwikiriwe igice cyubwoya bwumuringa binyuze muburyo bwo gutunganya. Nuburyo bumwe bwo gutondekane buringaniye, ariko igiciro cyumukora umusaruro kirenze ibyorezo byumubiri, urashobora guhitamo kubikoresha wenyine.
4. Gupfukaho umuringa no kubura: ni intambwe yanyuma yimikorere yose yo gutoragura umuringa. Nyuma yo gutakarura umuringa birangiye, umuringa wumuringa ugomba gukandamizwa hejuru yinama yumuzunguruko kugirango ihuze burundu, bityo iyemeza neza imyitwarire kandi yizewe kubicuruzwa.
二. Uruhare rw'umuringa
1. Gabanya ingaruka zimigozi yubutaka no kunoza ubushobozi bwo kurwanya ihohoterwa;
2. Mugabanye ikibazo voltage no kunoza imbaraga;
3. Ihuze insinga yubutaka kugirango ugabanye agace;
三. Ingamba zo gusuka umuringa
1. Ntusuke umuringa ahantu hafunguye insinga mu kigo cyo hagati cyinama ya Multilayer.
2. Kubintu bimwe-bimwe-bihuriye nibice bitandukanye, uburyo ni uguhuza kugeza 0 ohm abasuzugura cyangwa amasaro ya magneti cyangwa amavuko.
3. Iyo utangiye igishushanyo mbonera, insinga zubutaka igomba kunyurwa neza. Ntushobora kwishingikirizaho wongeyeho vias nyuma yo gusuka umuringa kugirango ukureho amapine adasanzwe.
4. Suka umuringa hafi ya kristu ya oscillat. Osichtal oscillattor mumuzunguruko nisoko yo hejuru-yohereza ibintu byinshi. Uburyo ni ugusuka umuringa hafi ya kristu ya osillator, hanyuma ubutaka bwa shell of orsillattor idasanzwe.
5. Menya neza ubwinshi no guhuriza hamwe umuringa wambaye umuringa. Mubisanzwe, umubyimba wumuringa wambaye umuringa uri hagati ya 1-2oz. Igice cy'umuringa kibi cyane cyangwa cyoroshye cyane kizagira ingaruka kumikorere itwara neza hamwe no kohereza ibimenyetso bya PCB. Niba urwego rw'umuringa rutaringaniye, ruzatera kwivanga no gutakaza ibimenyetso by'umuzunguruko ku kibaho cy'umuzunguruko, kibangamira imikorere no kwizerwa kwa PCB.
