Msika wamagetsi wamagalimoto ndi gawo lachitatu lalikulu kwambiri logwiritsa ntchito ma PCB pambuyo pa makompyuta ndi kulumikizana. Monga magalimoto asintha pang'onopang'ono kuchokera kuzinthu zamakina mwachikhalidwe kukhala zinthu zapamwamba kwambiri zomwe zili zanzeru, zodziwitsidwa, komanso zamakina, ukadaulo wamagetsi wagwiritsidwa ntchito kwambiri pamagalimoto, kaya ndi injini kapena makina a chassis, zida zamagetsi ndizomwe zimagwiritsidwa ntchito kwambiri pamagalimoto. amagwiritsidwa ntchito m'makina otetezera, machitidwe azidziwitso, ndi machitidwe ozungulira magalimoto. Msika wamagalimoto wasanduka malo ena owala pamsika wamagetsi ogula. Kukula kwa zamagetsi zamagalimoto mwachilengedwe kwayendetsa chitukuko cha ma PCB agalimoto.

M'mapulogalamu amasiku ano a PCB, ma PCB amagalimoto amakhala ndi udindo wofunikira. Komabe, chifukwa cha malo apadera ogwirira ntchito, chitetezo ndi zofunikira zamakono zagalimoto, zofunikira zake pa kudalirika kwa PCB ndi kusinthasintha kwa chilengedwe ndizokwera, ndipo mitundu yaukadaulo wa PCB nawonso ndi yotakata. Iyi ndi nkhani yaikulu kwa makampani PCB. Zovuta; komanso kwa opanga omwe akufuna kupanga msika wamagalimoto a PCB, kumvetsetsa komanso kusanthula msika watsopanowu ndikofunikira.

Ma PCB agalimoto amatsindika kudalirika kwambiri komanso kutsika kwa DPPM. Ndiye, kodi kampani yathu ili ndi luso laukadaulo komanso luso lopanga zodalirika kwambiri? Kodi zikugwirizana ndi momwe zinthu zidzakhalire m'tsogolomu? Pankhani yowongolera njira, kodi zitha kuchitidwa molingana ndi zofunikira za TS16949? Yapeza DPPM yotsika? Zonsezi ziyenera kufufuzidwa mosamala. Kungowona keke yoyesa iyi ndikulowa mwachimbulimbuli kubweretsa vuto kubizinesiyo.

Zotsatirazi zimapereka gawo loyimira machitidwe ena apadera popanga makampani amagalimoto a PCB panthawi yoyeserera kwa ambiri a PCB anzawo kuti afotokoze:

1. Njira yoyesera yachiwiri
Ena opanga ma PCB amatengera "njira yoyesera yachiwiri" kuti apititse patsogolo kuchuluka kwa ma board omwe alibe vuto pambuyo pakuwonongeka koyamba kwamagetsi amphamvu kwambiri.

2. Bad board foolproof dongosolo mayeso
Ochulukirachulukira opanga ma PCB ayika "dongosolo labwino lolembera zolemba" ndi "bokosi loyipa lotsimikizira zolakwika" mumakina oyesera a board kuti apewe kutayikira kwamunthu. Dongosolo labwino lolemba zilembo limawonetsa bolodi yoyesedwa ya PASS pamakina oyesera, omwe angalepheretse bwino bolodi loyesedwa kapena bolodi loyipa kuti lisalowe m'manja mwa makasitomala. Bokosi lolakwika la zolakwika za bolodi ndiloti panthawi yoyesedwa, pamene gulu la PASS likuyesedwa, dongosolo loyesera limatulutsa chizindikiro kuti bokosilo latsegulidwa; mwinamwake, pamene bolodi loipa liyesedwa, bokosilo limatsekedwa, kulola woyendetsa kuyika bolodi loyesedwa bwino.

3. Khazikitsani dongosolo la khalidwe la PPm
Pakali pano, PPm (Partspermillion, magawo pa miliyoni chilema) dongosolo khalidwe wakhala chimagwiritsidwa ntchito opanga PCB. Pakati pa makasitomala ambiri a kampani yathu, kugwiritsa ntchito ndi kupindula kwa Hitachi ChemICal ku Singapore ndizoyenera kutchulidwa. Mu fakitale, pali anthu oposa 20 amene ali ndi udindo kusanthula ziwerengero pa Intaneti PCB zachilendo khalidwe ndi PCB khalidwe abnormalies kubwerera. Pogwiritsa ntchito njira yowunikira mawerengero a SPC, bolodi lililonse losweka ndi bolodi lililonse lobwezeredwa losalongosoka limasankhidwa kuti liwunikenso mawerengero, ndikuphatikizidwa ndi ma micro-slicing ndi zida zina zothandizira kusanthula momwe zinthu zopangira bolodi yoyipa ndi yolakwika imapangidwira. Malinga ndi zotsatira za ziwerengero, kuthetsa mwadala mavuto mu ndondomekoyi.

4. Njira yofananira yoyesera
Makasitomala ena amagwiritsa ntchito mitundu iwiri yamitundu yosiyanasiyana poyesa kuyerekeza kwamagulu osiyanasiyana a PCB, ndikutsata PPm yamagulu ofananirako, kuti amvetsetse momwe makinawo amagwirira ntchito, ndikusankha makina oyezetsa ntchito kuti ayese ma PCB agalimoto. .

5. Sinthani magawo a mayeso
Sankhani magawo apamwamba a mayeso kuti muzindikire ma PCB otere. Chifukwa, ngati inu kusankha apamwamba voteji ndi pakhomo, kuonjezera chiwerengero cha mkulu-voteji kuwerenga kutayikira, akhoza kusintha mlingo kudziwika wa PCB zosalongosoka bolodi. Mwachitsanzo, kampani yayikulu yaku Taiwan ya PCB ku Suzhou idagwiritsa ntchito 300V, 30M, ndi 20 Euro kuyesa ma PCB agalimoto.

6. Nthawi ndi nthawi kutsimikizira magawo makina mayeso
Pambuyo pakugwira ntchito kwanthawi yayitali kwa makina oyesera, kukana kwamkati ndi magawo ena oyeserera adzapatutsidwa. Chifukwa chake, ndikofunikira kusintha magawo a makina nthawi ndi nthawi kuti muwonetsetse kulondola kwa magawo a mayeso. Zida zoyesera zimasungidwa m'mabizinesi akuluakulu a PCB kwa theka la chaka kapena chaka, ndipo magawo amkati amasinthidwa. Kufunafuna "zero chilema" PCBs kwa magalimoto wakhala malangizo a khama la anthu ambiri PCB, koma chifukwa cha malire a zipangizo ndondomeko ndi zipangizo, pamwamba 100 PCB makampani padziko lonse akadali kufufuza njira. kuchepetsa PPm.
