Umgangatho wokuhlolwa kwebhodi yePCB

ImiGangatho yokuHlola yeBhodi yeSekethe

1. Umda ufanelekile ukuhlolwa okungenayo kweebhodi zeesekethe ze-HDI zefowuni.

2. Isicwangciso sesampulu siya kuhlolwa ngokwe-GB2828.1-2003, inqanaba lokuhlolwa ngokubanzi II.

3. Uhlolo lusekelwe kwiinkcukacha zobugcisa obukrwada kunye neesampuli zokuhlola.

4. Inqanaba lomgangatho ofanelekileyo lisekelwe kwixabiso le-AQL: Iklasi A = 0.01, iKlasi B = 0.65, iKlasi C = 2.5.

5. Izixhobo zokuvavanya kunye nezixhobo: i-plug gauge, i-vernier caliper, i-oven ye-reflow, i-dynamometer, iglasi yokukhulisa, i-multimeter yedijithali, ubushushu obungaguqukiyo kunye nebhokisi yokufuma, umvavanyi obalulekileyo wobomi, umvavanyi wegolide ocwecwe ukutyeba, ilitye lebhastile elisicaba okanye iglasi, umvavanyi wokumelana nobushushu, ubushushu obuqhubekayo be-ferrochrome.

6. Ukuhlelwa kwesiphene: inombolo ye-serial inombolo yokuhlola Inkcazo yesiphene Ukupakishwa kwangaphandle kumanzi, izixhobo zibekwe kwindawo yokuphazamiseka Udidi lweSiphene Amanqaku e-CB 1 Akukho ileyibhile ngaphakathi okanye ngaphandle kwephakheji, ileyibhile engalunganga, ithontsi lamanzi ngaphakathi, akukho amaso angangenwa bumanzi, akukho khadi lokufuma. , izinto ezixubileyo, akukho Package ye-vacuum.

Ingxelo yokuthunyelwa kwe-1 ayibonelelwanga.Ingxelo yokuthunyelwa kwefektri

2. Izinto zokuhlola kwingxelo yokuthunyelwa komenzi azihambelani kwaye zizalisekile ngokweemfuno zethu zomgangatho wokuhlola, idatha yovavanyo ayihambelani neemfuno ezisemgangathweni, ingxelo ayinakuvunywa kumphathi womgangatho okanye kubasebenzi benqanaba eliphezulu, kunye nengxelo. umxholo bubuxoki, njl. Ukuba ezi mfuno zingasentla azihlangatyezwanga.Izinto zokuhlola inombolo ye-serial ye-serial Inkcazo yesiphene ngokubanzi Izinto ezingenayo zihluke kumenzi wesampuli, inombolo yepleyiti eyahlukileyo, ipleyiti eyahlukileyo (kubandakanywa nokuchonga ipleyiti), akukho mjikelezo wemveliso, kwaye akukho mgangatho wefektri.Kufuneka kungabikho ziphelo ezibukhali ezijikeleze i-PCB ukuchaphazela udibaniso kunye nokwenzakalisa umqhubi.I-Porous kunye ne-pores encinci I-pores enkulu kunye encinci (ngokweemfuno zemizobo yoyilo) Kukho ubhedu obuseleyo kwi-NPTH hole, kwaye kukho i-oxidation emngxunyeni.) indawo egqityiweyo yokuvula: ukuba ingaphezulu kweemfuneko ezingezantsi

I-3 yokugaya imingxuma ejikelezayo: NPTH: +/-2mil (+/-0.05mm);I-NPTH: umngxuma wobhedu ongazikiyo B;I-PTH: umngxuma wobhedu ozikayo PTH: +/-3mil (+/-0.075mm) 2,
