Ukuqinisekisa umgangatho opheleleyo we- aluminium substrate PCB , ukuba i-solder ekumgangatho ophezulu kufuneka isetyenziswe kwinkqubo yemveliso ukuphucula ukwenziwa kwe-welding ye-PCB kunye nokuthintela i-warpage kunye ne-defect.So, zeziphi izinto ezibangela ukusilela kwe-PCB kwi-aluminium substrate? Landela abavelisi abaqeqeshiweyo be-PCB yeYongmingsheng ukuze baqonde.

1. Ukufakwa kwemingxunya kwibhodi yesekethe kunefuthe kumgangatho we-welding.

Ngenxa yokuthengiswa kakubi komngxunya webhodi yesekethe, kuyakubakho iziphene ze-welding, ezichaphazela iiparitha zezinto kwisekethe, zibangele izixhobo kunye nomaleko wangaphakathi wokungazinzi komgca wokuhamba, okukhokelela ekusebenzeni konke ukusilela kwesekethe .

2. Iziphene ze-Welding ezibangelwa kukujijisana.

Ibhodi yesekethe kunye namacandelo aya kusonta kwinkqubo yokuwelda, kwaye uxinzelelo kunye nokudodobala kuya kukhokelela kwi-welding ebonakalayo, isekethe emfutshane kunye nezinye iziphene.Ukulwa kudla ngokubangelwa ngumgangatho wobushushu phakathi kwamacandelo aphezulu kunye asezantsi ebhodi yesekethe. I-polypropylene, ibhodi yentsimbi ngenxa yesisindo sayo.

3. Uyilo lwebhodi yesekethe luchaphazela umgangatho we-welding.

Ukusuka kwindawo yoyilo, ubukhulu bebhodi yesekethe bukhulu kakhulu, nangona i-welding kulula ukuyilawula, kodwa umgca oprintiweyo mde, ukunyuka kwemithambo kuyenyuka, iindleko ziyanda; Ubungakanani bincinci kakhulu, ukusasazeka kobushushu kuncitshisiwe, i-welding akukho lula ukuyilawula, kwaye ukuphazamiseka okuhambelana kwemigca emelene nayo kulula ukwenzeka.

Ke uyilo lwebhodi ye-PCB kufuneka yenziwe:

A. Kucutha unxibelelwano phakathi kwezinto ezihamba rhoqo kunye nokunciphisa ukuphazamiseka kwe-electromagnetic.

B. Kwizinto ezinzima, zilungise ngeebakaki kwaye emva koko uzidibanise.

C. Izinto zobushushu kufuneka zithathelwe ingqalelo ukusasazeka kobushushu, izinto ezishushu kufuneka zikude nomthombo wobushushu.

Amacandelo acwangciswe ngokuhambelana kangangoko kunokwenzeka, ayisiyontle kuphela, kodwa kulula ukuyinyibilikisa kwaye ilungele ukuveliswa kobuninzi.Uyilo olululo lwebhodi yesekethe luxande oluyi-4∶3. ngequbuliso kwaye uphephe ukusebenzisa iindawo ezinkulu zephepha lobhedu.

Oku kungunobangela wesiphene se-welding kwi-PCB ye-aluminium substrate. Ndiyathemba ukuba inokukunceda.
