Ngiqinisekisa kanjani ukwethembeka kwe-vias ebhodini lesekethe eliguquguqukayo eliqinile?

Isingeniso:

Kulokhu okuthunyelwe kwebhulogi, sizohlola obunye bobuchwepheshe obubalulekile nezindlela ezihamba phambili ongazisebenzisa ukuze uqinisekise ukwethembeka kwe-vias kumabhodi esekethe aqinile.
Lapho uklama amabhodi wesifunda, ukwethembeka kubalulekile. Isici esibalulekile esidinga ukucatshangelwa kahle ukwethembeka kwe-vias kumabhodi wesekethe aguquguqukayo. I-Vias idlala indima ebalulekile ekusunguleni ukuxhumana phakathi kwezingqimba ezihlukene zesekhethi kanye nokuqinisekisa ukuhamba kahle kwamasignali kagesi.

Ngaphambi kokungena emininingwaneni, kubalulekile ukuqonda umqondo oyisisekelo we-vias. I-Vias yizimbobo ezincane ezibhobozwe ngokufakwa kwebhodi lesekethe ukuvumela ukuxhumana kukagesi phakathi kwezingqimba ezihlukene. Emabhodini esekethe aqinile ahlanganisa ama-substrates aguquguqukayo futhi aqinile, i-vias kufanele yakhelwe ukumelana nezingcindezi kanye nobunzima obuhambisana nokugoba nokugoba.

Ukuqinisekisa ukuthembeka kwe-vias kumabhodi wesekethe aqinile, nazi ezinye izinto eziyisisekelo:

1. Lungisa ngokubeka:
Indawo kanye nokusatshalaliswa kwe-vias kubalulekile ekugcineni ukwethembeka. Kubalulekile ukubeka i-vias ezindaweni zesekhethi ngokugoba nokugoba okuncane. Lokhu kusiza ukunciphisa ukucindezeleka kuma-vias futhi kuvimbele ukuba bangonakaliswe ngesikhathi sokuphila kwebhodi.

2. Ngosayizi nokubukeka kwesilinganiselo:
Usayizi nokubukeka kwesilinganiso se- via nakho kuthinta ukuthembeka kwayo. Ama-diameter amancane angenwa kalula yingcindezi yemishini futhi amelana kakhulu nokwehluleka. Ukwengeza, i-aspect ratio (isilinganiso sokujula kuya ku-diameter) kufanele sibe ngaphakathi kwemikhawulo eyamukelekayo ukuze kuvinjelwe izinkinga ezifana nama-plating voids noma imifantu.

3. Idizayini yephedi nendandatho:
Idizayini yephedi nendandatho ezungeze i-via idlala indima ebalulekile ekuthembekeni kwayo. Iphedi eyanele kanye nobukhulu bendandatho kufanele kugcinwe ukuze kuqinisekiswe amajoyinti athembekile e-solder kanye nokuxhumeka okufanele kukagesi. Amaphedi amancane noma amaringi angabangela ukuxhumeka kwemishini okubuthakathaka kanye nezinkinga zikagesi.

4. Ukusetshenziswa ngokusebenzisa izimbobo:
Emabhodini esekethe aqinile, kunconywa ukuthi asetshenziswe emigodini esikhundleni se-vias eyimpumputhe noma egqitshiwe noma nini lapho kunokwenzeka. Ngezimbobo zinikeza amandla angcono wemishini kanye nokuxhumana kukagesi. Baphinde bavumele ukuhlolwa nokuhlolwa okulula phakathi nenqubo yokukhiqiza.

5. Ukukhetha impahla:
Ukukhetha into efanele ye-via kubalulekile ekuthembekeni kwayo. Izinto ezisezingeni eliphezulu njengethusi elingena-electroless noma i-nickel plating (i-nickel engena-electroless, i-electroless palladium, i-immersion gold) ingakhuphula ukuqina nokuhlala isikhathi eside kwezimbobo, ikakhulukazi ezimweni ezinzima zemvelo.

6. Ukuphathwa kokushisa:
Ukuphatha okushisayo okufanelekile kungase futhi kuthuthukise ukwethembeka kwe-vias kumabhodi wesekethe aqinile-flex. Ama-vias abekwe kahle asiza ukuqeda ukushisa, anciphise ubungozi bokulimala okushisayo ebhodini nasezintweni zalo.

7. Ukuthobela izindinganiso zomkhakha:
Ukulandela izindinganiso zomkhakha kanye nokucaciswa kubalulekile ekuqinisekiseni ngokwethembeka. Amazinga afana ne-IPC-2223 anikeza isiqondiso ngokuklama, izinto zokwakha, nokusebenzisa. Ukubambelela kulawa mazinga kuqinisekisa ukuhambisana futhi kukhulisa ukuthembeka kukonke kwebhodi.

8. Ukuhlola nokuhlola okuqinile:
Ukuhlolwa okuphelele nokuhlolwa kwamabhodi esekethe aqinile, okuhlanganisa i-vias, kubalulekile ukuze kutholwe noma yiziphi izinkinga ezingase zibe khona ngaphambi kokuthunyelwa. Izindlela zokuhlola ezingalimazi njengokuhlola i-X-ray zingasiza ekuhlonzeni noma yikuphi ukonakala noma okungahambi kahle ku-Vis ukuze kuthathwe isinyathelo sokulungisa ngokushesha.

Ngokusebenzisa lezi zindlela ezingcono kakhulu nokucatshangelwa, abaklami bangathuthukisa kakhulu ukuthembeka kwe-vias kumabhodi wesekethe aqinile. Kubalulekile ukusebenza nomkhiqizi onolwazi futhi uxhumane nochwepheshe kulo mkhakha ukuze uqinisekise ukuthi umklamo othembekile noqinile uyasetshenziswa.

Ngokufigqiwe

Ukuthembeka kwe-vias kumabhodi wesekethe e-rigid-flex kubalulekile futhi kudinga ukunakwa ngokucophelela. Ngokufanele ngesakhiwo, usayizi nokuklama, ukukhethwa kwezinto ezibonakalayo, ukuphathwa kwezimo ezishisayo, ukuhambisana nezindinganiso zemboni nokuhlola okuqinile, abaklami bebhodi lesifunda bangaqinisekisa impumelelo nokuthembeka kwamaphrojekthi abo. Ukutshala isikhathi nomzamo ekuthuthukiseni amadizayini embobo kuzoholela ekusebenzeni kangcono, amabhodi aqinile aqinile.
