Ukuze kuqinisekiswe ikhwalithi ephelele ye- aluminium substrate PCB , lelo solder esezingeni eliphakeme kufanele lisetshenziswe kwinqubo yokukhiqiza ukwenza ngcono ukusebenza kwe-Welding kwe-PCB nokuvikela i-warpage ne-defect.So, yiziphi izimbangela zokukhubazeka kwe-PCB welding ku-aluminium substrate? Landela abakhiqizi be-aluminium PCB abaqeqeshiwe beYongmingsheng ukuqonda.

1. Ukushiswa komgodi webhodi lesifunda kunomthelela kuzinga le-welding.

Ngenxa yokungathengiseki kahle komgodi webhodi lesifunda, kuzoba khona ukukhubazeka kwe-welding okubonakalayo, okuthinta amapharamitha wezinto eziseseketini, kubangele izingxenye kanye nongqimba lwangaphakathi lokungazinzi komugqa wokuqhuba, okuholele ekusebenzeni kukonke kokwehluleka kwesifunda .

2. Welding amaphutha okubangelwa warping.

Ibhodi lesifunda nezinto zalo zizogudlukela enqubeni yokushisela, futhi ingcindezi nokukhubazeka kuzoholela ekushiseni kwe-virtual, isifunda esifushane nokunye ukukhubazeka. Ukulwa kuvame ukubangelwa ibhalansi lokushisa phakathi kwezingxenye ezingenhla nezingezansi zebhodi lesifunda. polypropylene, ibhodi iyagoqeka ngenxa yesisindo sayo.

3. Idizayini yebhodi lesifunda ithinta ikhwalithi yokushisela.

Ngokombono wedizayini, usayizi webhodi lesifunda mkhulu kakhulu, yize i-welding kulula ukuyilawula, kepha ulayini ophrintiwe mude, impedance iyanda, izindleko ziyanda; Usayizi mncane kakhulu, ukushabalalisa ukushisa kunciphile, i-welding akulula ukuyilawula, futhi ukuphazamiseka kokuhlangana kwemigqa eseduze kulula ukwenzeka.

Ngakho-ke ukwakheka kwebhodi le-PCB kufanele kulungiselelwe:

A. Yehlisa ukuxhumana phakathi kwezakhi zemvamisa ephezulu futhi yehlisa ukuphazamiseka kwe-electromagnetic.

B. Ngezingxenye ezisindayo, zilungise ngabakaki bese uzihlanganisa.

C. Izinto ezishisayo kufanele zibhekwe njengokushiswa kokushisa, izinto ezishisayo kufanele zibe kude nomthombo wokushisa.

Izakhi zihlelwe ngokulingana ngangokunokwenzeka, okungekuhle kuphela, kepha futhi okulula uku-weld futhi kufanelekile ekukhiqizweni ngobuningi.Idizayini enhle kakhulu yebhodi lesifunda ingunxande ongu-4∶3.Ungashintshi ububanzi bocingo ngokuzumayo futhi ugweme ukusebenzisa izindawo ezinkulu zocwecwe lwethusi.

Lokhu okungenhla kuyimbangela yokukhubazeka kwe-welding ku-PCB ye-aluminium substrate. Ngiyethemba ukuthi ingakusiza kuwe.Sivela kumhlinzeki we-aluminium substrate waseChina - uYongmingsheng Electronics, wamukelekile ukubonisana!
