Ezinye izinkinga nendlela yokulawula PCB I-plug mechanism yilokho abantu abaningi abafuna ukukwazi, ngakho-ke lesi sihloko sikulethela lolu lwazi.

Okokuqala, imbangela yenkinga

Ngokuthuthuka okuqhubekayo kokunemba kokukhiqiza kwabakhiqizi be-PCB, abakhiqizi bamabhodi wesekethe nge-hole akhiqizwe amasekhethi e-PCB aphrintiwe aya ngokuya eba mancane ngokuba mancane. Mayelana namabhodi okukhiqiza abhobozwe ngomshini, ngokusebenzisa izimbobo ezinobubanzi obungu-0.3mm ajwayelekile, kanti u-0.25mm noma u-0.15mm nawo awupheli. Njengoba imbobo iyancipha, kuba ipulaki elihlala phakathi kwembobo. Ngemva kokuxhuma imbobo, ipuleti livame ukuphuka ngaphandle kokuphuka. Isilinganiso sikagesi asikwazi ukukala isisekelo, futhi ekugcineni sigeleza singene kuklayenti. Ngemuva kokushisela izinga lokushisa eliphezulu, ukushaqeka okushisayo ngisho nokuhlangana, isicelo sise-East Window kuphela. Sekwephuze kakhulu ukuzindla ngakho manje!

Uma ungaqala ngenqubo yokukhiqiza, ungasebenzisa amapulaki embobo ngayinye ngayinye ukuze uvimbele ukuvaleka okubi. Lokhu kuzoba yindlela engcono kakhulu yokuthuthukisa ikhwalithi. Mina ngokwami ​​ngizamile ukuxoxa ngendlela yamanye amapulaki enqubeni, futhi nginikeze izindlela ezithile zokusebenza eziwusizo ukuvimbela noma ukunciphisa ukwenzeka kokuvala okubi.

Okwesibili, hlaziya amapulaki embobo embi kunqubo ngayinye

Sonke siyazi ukuthi abakhiqizi be-PCB banokubhoboza, ukususa i-degumming, i-copper plating, i-plating, i-graphics processing, i-graphics plating nezinye izinqubo ezinkulu ekukhiqizeni ibhodi lesifunda eliphrintiwe le-PCB kanye nokucutshungulwa kwemigodi. Ngakho-ke, ukulungiswa kwepulaki yembobo nakho ngizokukwenza ngamunye ngamunye. Yethula inqubo ngayinye.

Drilling

Amapulaki embobo abangelwa ukubhoboza ikakhulukazi anezinhlobo ezilandelayo, futhi izingcezu zento ziboniswa esithombeni esingezansi.

Fingqa

Ake sifingqe: Naphezu kwalokhu, umuntu wami akabholi kakhulu. Kodwa-ke, empeleni, ukubhoboza kusengenye yezigameko eziyinhloko zokuxhuma kabi. Ngokocwaningo lwezibalo zombhali, kutholakala ukuthi u-35% wemigodi akanalo ithusi, kanti ukuxhuma imbobo okubangelwa ukubhoboza kubi kakhulu. Ngakho-ke, ukulawula ukumba kugxile ekulawuleni okungalungile kwepulaki. Ngicabanga ukuthi izici ezilandelayo zingamaphuzu okulawula ayinhloko:

1. Ngokwemiphumela yokuhlola, kunokuba ochwepheshe bendabuko bathembele ekuhlangenwe nakho kokuqeqeshelwa umsebenzi ukuhlonza imingcele yokumba enengqondo (ummese ongezansi uyashesha kakhulu futhi ipulaki ilula);

2. Ukulungiswa kwesikhathi se-drilling rig;

3. Qinisekisa ukuqoqwa kothuli;

4. Kubalulekile ukwazi ukuthi i-drill bit ibhoboza izimbobo ku-tape ukuletha iglue emgodini, kunokuba ifake i-tape ngokwayo emgodini. Ngakho-ke, i-drill akufanele ibhojwe ku-tape nganoma yisiphi isikhathi;

5. Yenza izindlela eziwusizo zokuthola izingcezu zokubhoboza eziphukile;

6. Abakhiqizi abaningi baye benza ama-pores wokuqoqa uthuli lomoya ophezulu we-high-pressure kanye nokwelashwa kokukhipha uthuli ngemva kokumba, okungase kusetshenziswe;

7. Inqubo yokususa ngaphambi kokucwila kwethusi kufanele kube ukugeza kwe-ultrasonic nokugeza okunomfutho ophezulu (ingcindezi engaphezu kuka-50KG/CM2).
