Isikhala sokuphepha sikagesi ikakhulukazi sincike ezingeni lefektri yokwenza amapuleti, okungu-0,15mm. Eqinisweni, ingasondela kakhulu. Uma umjikelezo awuhlobene nesiginali, inqobo nje uma kungekho umjikelezo omfushane futhi okwamanje kwanele, kwamanje kwanele kudinga izintambo ezibanzi nezikhala.
1.Izincwadi eziphakathi kwezintambo
Ibanga phakathi kwabaqhubi lidinga ukubhekwa ngokususelwa kukhono lokukhiqiza le-PCB. Kunconywa ukuthi ibanga phakathi kwabaqhubi bangaba okungenani i-4mil. Kodwa-ke, amafektri athile angakhiqiza ngobubanzi be-3 / 3mil ulayini kanye nokuhlukaniswa komugqa. Ngokombono wokukhiqizwa, kunjalo, okukhulu kakhulu ngaphansi kwezimo. I-6mil ejwayelekile engu-6mil ijwayelekile ngokwengeziwe.
2.Spacing phakathi kwePad nocingo
Ibanga phakathi kwePad nomugqa ngokuvamile abungaphansi kwe-4mil, futhi ibanga elikhudlwana phakathi kwepadi nomugqa lapho kunesikhala, okungcono. Ngoba i-Pad Welding idinga ukuvulwa kwewindows, ukuvulwa kwewindows kukhulu kune-2mil yePad. Uma izikhala zinganele, ngeke kubangele umjikelezo omfushane we-line ungqimba, kepha futhi kuholele ekuvezweni kwethusi komugqa.
3.I-spacesing phakathi kwe-pad ne-pad
Isikhala phakathi kwe-pad ne-pad kufanele kube nkulu kune-6mil. Kunzima ukwenza ibhuloho le-solder stop-welding nge-pad spaceding enganele, futhi i-IC Pad Pad yamanethiwekhi ahlukile angaba nomjikelezo omfushane lapho i-welding ilibhuloho elivulekile. Ibanga phakathi kwepakethe lenethiwekhi futhi i-pad lincane, futhi alikho lula ukudicilela phansi izingxenye ezilungisiwe ngemuva kokuthi i-tin ixhumeke ngokuphelele e-welding.
I-4.Copper ne-Copper, i-Wire, i-Pad Spacesing
Ibanga phakathi kwesikhumba sethuli bukhoma nomugqa futhi pad likhulu kunalokho phakathi kwezinye izinto zomugqa, kanye nebanga phakathi kwesikhumba sethusi nomugqa kanye ne-pad kukhulu kune-8mil ukwenza lula ukukhiqizwa nokwenziwa. Ngoba usayizi wesikhumba sethusi akudingeki ukuthi wenze inani eliningi, likhulu futhi elincane alinandaba. Ukuze uthuthukise isivuno sokukhiqiza semikhiqizo, ukuhlukaniswa kwezikhala phakathi komugqa kanye ne-pad kusuka esikhunjeni sethusi kufanele kube makhulu ngangokunokwenzeka.
I-5.Spaceng of wire, pad, ithusi kanye nomphetho wepuleti
Ngokuvamile, ibanga phakathi kwentambo, i-pad kanye nesikhumba sethusi kanye nomqondo we-contour kufanele kube mkhulu kune-10mil, futhi ngaphansi kwama-8mil kuzoholela ekuchayweni kwethusi onqenqemeni lwepuleti ngemuva kokukhiqizwa nokubumba. Uma umphetho wepuleti u-v-cut, khona-ke izikhala kufanele zibe zinkulu kune-16mil. I-Wire nePad akuwona kuphela ithusi elilula kakhulu, umugqa osondele kakhulu emaphethelweni epuleti angaba mncane, okuphumela ezinkingeni zokuthwala zamanje, kutholakale i-welding empofu .`
