1. Mayeso amagetsi

Popanga ndondomeko ya PCB bolodi, n’zosapeŵeka kuti kuwonongeka kwa magetsi monga maulendo afupikitsa, maulendo otseguka ndi kutuluka chifukwa cha zinthu zakunja zidzayamba. Kuphatikiza apo, PCB ikupitilizabe kusinthika kupita ku kachulukidwe kwambiri, mamvekedwe abwino komanso magawo angapo. Ngati matabwa osalongosoka sanachotsedwe mu nthawi Kuwunika kunja, ndi kulola kuti kuyenda mu ndondomeko, mosalephera kuwononga ndalama zambiri. Choncho, kuwonjezera pa kusintha kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.

Popanga zinthu zamagetsi, kutayika kwa mtengo komwe kumachitika chifukwa cha zolakwika kumakhala ndi magawo osiyanasiyana pagawo lililonse. Kuzindikira koyambirira kumakhala, kutsika mtengo wokonzanso. “Lamulo la 10’s” nthawi zambiri limagwiritsidwa ntchito poyesa mtengo wokonzanso pamene ma PCB amapezeka kuti ali ndi vuto pamagawo osiyanasiyana akupanga. Mwachitsanzo, pambuyo pa bolodi lopanda kanthu, ngati dera lotseguka mu bolodi likhoza kudziwika mu nthawi yeniyeni, nthawi zambiri zimangofunika kukonzanso mzerewo kuti zithetse vutolo, kapena pa bolodi limodzi lopanda kanthu limatayika; koma ngati dera lotseguka silinazindikiridwe, dikirani kuti bolodi itumizidwe Pamene osonkhanitsa kumtunda akumaliza kuyika zigawozo, ng’anjo ya ng’anjo ndi IR zimatsitsimutsidwa, koma panthawiyi zimadziwika kuti dera latsekedwa. Wophatikizira kunsi kwa mtsinje adzafunsa kampani yopanda kanthu yopanga ma board kuti ilipire mtengo wa magawo ndi ntchito zolemetsa. , Malipiro oyendera, etc. Ngati ziri zomvetsa chisoni kwambiri, bolodi lopanda pake silinapezeke muyeso la assembler, ndipo limalowa m’dongosolo lonse lomaliza mankhwala, monga makompyuta, mafoni a m’manja, mbali zamagalimoto, ndi zina zotero. nthawi, kutayika komwe kunapezeka ndi mayeso kudzakhala bolodi yopanda kanthu munthawi yake. Nthawi zana, chikwi chimodzi, kapena kupitilira apo. Chifukwa chake, kwamakampani a PCB, kuyezetsa kwamagetsi ndikuzindikira msanga zolakwika zamagawo.

Osewera otsika nthawi zambiri amafuna opanga PCB kuti achite kuyezetsa magetsi kwa 100%. Chifukwa chake, onse awiri adzafotokozera momveka bwino zinthu izi:

1. Gwero la kuyesa ndi mawonekedwe

2. Mikhalidwe yoyesera, monga magetsi, zamakono, zotsekemera ndi kugwirizanitsa

3. Njira yopanga zida ndi kusankha

4. Chaputala choyesa

5. Kukonza ndondomeko

Popanga PCB, pali magawo atatu omwe ayenera kuyesedwa:

1. Pambuyo wosanjikiza wamkati wakhazikika

2. Pambuyo pa dera lakunja lokhazikika

3. Anamaliza mankhwala

Pa gawo lililonse, nthawi zambiri pamakhala 2 mpaka 3 kuyesa kwa 100%, ndipo matabwa opanda pake amawunikiridwa ndikukonzedwanso. Chifukwa chake, malo oyeserera ndiwonso gwero labwino kwambiri losonkhanitsira deta powunikira zovuta zamachitidwe. Kupyolera mu zotsatira za ziwerengero, kuchuluka kwa mabwalo otseguka, maulendo afupikitsa ndi mavuto ena otsekemera amatha kupezeka. Pambuyo pa ntchito yolemetsa, kuyendera kudzachitika. Deta ikasanjidwa, njira yoyendetsera bwino ingagwiritsidwe ntchito kupeza Kuthetsa vuto lomwe limayambitsa vutoli.

2. Njira zoyezera zamagetsi ndi zida

Njira zoyezera magetsi zimaphatikizapo: Kudzipereka, Gulu Lonse Lalikulu, Flying Probe, E-Beam, Conductive Cloth (Glue), Capacity And brush test (ATG-SCANMAN), yomwe ili ndi zida zitatu zomwe zimagwiritsidwa ntchito kwambiri, zomwe ndi makina apadera oyesera, mayeso wamba. makina oyendetsa ndege ndi makina oyendetsa ndege. Kuti mumvetse bwino ntchito za zipangizo zosiyanasiyana, zotsatirazi zidzafanizira makhalidwe a zipangizo zazikulu zitatu.

1. Mayeso odzipereka

Kuyesa kwapadera ndi kuyesa kwapadera makamaka chifukwa chogwiritsidwa ntchito (chikhazikitso, monga mbale ya singano poyesa magetsi pa bolodi la dera) ndi yoyenera pa nambala imodzi yazinthu, ndipo ma board a manambala osiyanasiyana sangathe kuyesedwa. Ndipo sichingabwezeretsedwenso. Pankhani ya mayeso, gulu limodzi likhoza kuyesedwa mkati mwa mfundo 10,240 ndi mbali ziwiri za 8,192 mfundo iliyonse. Pankhani ya kachulukidwe ka mayeso, chifukwa cha makulidwe a mutu wa probe, ndiyoyenera kwambiri pa bolodi yokhala ndi phula kapena kupitilira apo.

2. Mayeso a Universal Grid

Mfundo yofunikira pakuyesa-cholinga chonse ndikuti masanjidwe a dera la PCB adapangidwa molingana ndi gululi. Kawirikawiri, zomwe zimatchedwa kachulukidwe ka dera zimatanthawuza mtunda wa gridi, womwe umasonyezedwa molingana ndi phula (nthawi zina ukhoza kufotokozedwa ndi kachulukidwe ka dzenje) ), ndipo kuyesa kwakukulu kumachokera pa mfundoyi. Malinga ndi malo a dzenje, zida zoyambira za G10 zimagwiritsidwa ntchito ngati chigoba. Chofufuza chokhacho chomwe chili pa dzenje chingadutse chigoba kuti chiyesedwe ndi magetsi. Choncho, kupanga chojambulacho ndi chophweka komanso chachangu, ndipo kafukufuku Singano ikhoza kugwiritsidwanso ntchito. Kuyesa kwa zolinga zonse kumakhala ndi mbale yokhazikika ya Gridi yokhazikika yokhala ndi miyeso yambiri. Ma mbale a singano a probe yosunthika amatha kupangidwa molingana ndi manambala azinthu zosiyanasiyana. Popanga misa, mbale ya singano yosunthika imatha kusinthidwa kukhala yochulukirapo pazinambala zazinthu zosiyanasiyana. mayeso.

Kuphatikiza apo, pofuna kuwonetsetsa kusalala kwa dongosolo lomalizidwa la PCB board, ndikofunikira kugwiritsa ntchito makina othamanga kwambiri (monga 250V) ma multipoint general-purpose electro test master kuti ayesetse Open/Short magetsi pa. bolodi yokhala ndi mbale ya singano yokhala ndi kukhudzana kwapadera. Makina oyesera amtundu woterewa amatchedwa “Automatic Testing Equipment” (ATE, Automatic Testing Equipment).

Mayeso oyeserera nthawi zambiri amakhala opitilira 10,000, ndipo mayesowo amakhala ndi kachulukidwe ka mayeso kapena amatchedwa mayeso a on-grid. Ngati ikugwiritsidwa ntchito pa bolodi lapamwamba kwambiri, ndiyopanda kupangidwa pa gridi chifukwa cha malo oyandikana kwambiri, choncho ndi ya off-grid Kuti muyesedwe, chowongoleracho chiyenera kupangidwa mwapadera, ndi kachulukidwe ka mayeso a cholinga chonse. kuyezetsa nthawi zambiri kumakhala mpaka QFP.

3. Mayeso a Flying Probe

Mfundo yoyesa mayeso owuluka ndi yosavuta. Zimangofunika ma probes awiri kuti musunthe x, y, z kuyesa mfundo ziwiri zomaliza za dera lililonse limodzi ndi limodzi, kotero palibe chifukwa chopangira ma jigs okwera mtengo. Koma chifukwa ndi mayeso omaliza, kuthamanga kwa mayeso kumakhala pang’onopang’ono, pafupifupi 10-40 mfundo / sec, kotero ndi koyenera kwa zitsanzo ndi kupanga pang’ono; pankhani ya kachulukidwe ka mayeso, kuyesa kwa probe kowuluka kumatha kugwiritsidwa ntchito pama board okwera kwambiri.
