Isithuba sokhuseleko lombane sixhomekeke ikakhulu kumgangatho wefektri yokwenza iipleyiti, edla ngokuba yi-0.15mm. Enyanisweni, inokuba isondele ngakumbi. Ukuba isekethe ayihambelani nomqondiso, ngokude nje kungekho mjikelezo omfutshane kwaye i-current yanele, umsinga omkhulu ufuna i-wiring ebanzi kunye nesithuba.
1.Umgama phakathi kweengcingo
Umgama phakathi kwee-conductor kufuneka uqwalaselwe ngokusekelwe kwisakhono somvelisi se-PCB sokwenza. Kucetyiswa ukuba umgama phakathi kwabaqhubi ube ubuncinane be-4mil. Nangona kunjalo, ezinye iifektri nazo zinokuvelisa nge-3/3mil yobubanzi bomgca kunye nesithuba semigca. Ngokwembono yemveliso, ngokuqinisekileyo, inkulu ingcono phantsi kweemeko. I-6mil eqhelekileyo iqhelekile.
2.Isithuba phakathi kwephedi kunye nocingo
Umgama phakathi kwepadi kunye nomgca ngokuqhelekileyo awukho ngaphantsi kwe-4mil, kwaye umgama omkhulu phakathi kwepadi kunye nomgca xa kukho indawo, kungcono. Ngenxa yokuba i-pad welding ifuna ukuvulwa kwefestile, ukuvuleka kwefestile kungaphezulu kwe-2mil ye-pad. Ukuba isithuba esinganelanga, asiyi kubangela kuphela isiphaluka esifutshane somgca womgca, kodwa sikhokelela ekubonakalisweni kobhedu komgca.
3.Isithuba phakathi kwePad nePad
Isithuba phakathi kwepadi kunye nephedi kufuneka sibe sikhulu kune-6mil. Kunzima ukwenza i-solder stop-welding bridge kunye ne-pad spacing eyaneleyo, kunye ne-IC pad yothungelwano oluhlukeneyo lunokuba neesekethe ezimfutshane xa udibanisa ibhulorho evulekileyo ye-weld. Umgama phakathi kwe-network pad kunye ne-pad incinci, kwaye akulungele ukukhupha izinto ezilungisiweyo emva kokuba i-tin idibene ngokupheleleyo kwi-welding.
4.Ubhedu kunye nobhedu, ucingo, i-PAD isithuba
Umgama phakathi kwesikhumba sobhedu esiphilayo kunye nomgca kunye ne-PAD inkulu kunoko phakathi kwezinye izinto zomgca womgca, kunye nomgama phakathi kwesikhumba sobhedu kunye nomgca kunye ne-PAD mkhulu kune-8mil ukuququzelela imveliso kunye nokuveliswa. Ngenxa yokuba ubukhulu besikhumba sobhedu akufuneki ukuba benze ixabiso elininzi, incinci encinci kwaye incinci ayinandaba. Ukuze kuphuculwe imveliso yemveliso yeemveliso, isithuba phakathi komgca kunye ne-PAD ukusuka kwesikhumba sobhedu kufuneka sibe sikhulu kangangoko kunokwenzeka.
I-5.Isithuba socingo, i-PAD, i-copper kunye ne-plate edge
Ngokuqhelekileyo, umgama phakathi kwe-wiring, i-pad kunye nesikhumba sobhedu kunye nomgca we-contour kufuneka ube mkhulu kune-10mil, kwaye ngaphantsi kwe-8mil iya kukhokelela ekuvezweni kobhedu kumda weplate emva kokuveliswa kunye nokubumba. Ukuba umphetho wepleyiti yi-V-CUT, ke isithuba kufuneka sibe sikhulu kune-16mil. Ucingo kunye ne-PAD azikho kuphela ubhedu oluveziweyo olulula, umgca osondele kakhulu kumphetho wepleyiti unokuba mncinci, okukhokelela kwiingxaki zokuthwala zangoku, i-PAD encinci ichaphazela i-welding, ekhokelela ekudibaniseni kakubi.
