Enye yezona mpazamo zixhaphakileyo ezenziwe ngexesha PCB ukuvelisa yinto engafanelekanga yokulandelelana, enokubangela ukuba yonke inkqubo isilele. Inkqubo yendibano ye-PCB inokusebenza ukusuka kwindawo yokuqhubekeka yombane, nokuba kungokuhlolwa kombane. Kuyilo, ukulandelelana kwenqwelomoya kunye nophawu lomqondiso kunye nomgama phakathi kweendlela ezikufutshane kubalulekile.

Ukuqinisekisa ukuba ulwazi ngemveliso luyafuneka ukwenza uhlolo oluchanekileyo lokulungiswa kwemaleko, abaqulunqi bePCB kufuneka bayile imeko echanekileyo yobhedu kwidatha yokuvelisa, oko kukuthi, ukufezekisa iodolo efanelekileyo. Ezi mpawu zobhedu zibonelela ngendlela yokuhlola izinto zokugqibela, nje ukuba kwenziwe uvavanyo lwe-Q & A lwangaphakathi, olucociweyo ukuya kwindawo yokuvelisa.

Ukuqwalaselwa kolwahlulo?

Umsebenzi wokuqala wobhedu owongezwe kulwahlulo ngalunye kukuchonga ulungelelwaniso olunxulumene nolunye uhla. Uluhlu ngalunye lufumana inamba yomaleko ethe nkqo ngqo kubhedu, ebonisa indawo ekuyo kwindawo yecascade, kunye nenombolo yomaleko kufuneka ibandakanywe kummandla wepleyiti egqityiweyo. Umaleko kufuneka ubekwe kufutshane nomda webhodi ukuze ungaphazamisi iimpawu zombane wesekethe. Ingathatha uhlobo lwenombolo enye kumaleko ngamnye. Kodwa amanani anokungangqinelani. Xa zonke iitshathi zokutshekisha zifakiwe, kufuneka zibonakale ngokucacileyo xa zijongwa phezulu phezulu.

Imaleko ihlala ibekwa kwiibhokisi eziziingxande ukuze kubonwe lula. Susa isigqumathelo se-welding kunye nomsebenzi wescreen kwindawo ejikeleze izaleko ukulungiselela ukubonwa komgangatho ngePCB epheleleyo ngomthombo wokukhanya wokuhlola obekwe emva kwendibano. Amacwecwe awanakudityaniswa kulo naluphi na umaleko kwimisebenzi yobhedu, njengaleyo yamandla okanye ipoligoni.

Izitampu zePCB ziimpawu zobhedu emaphethelweni e-PCB ukuququzelela ukuhlolwa okubonwa ngokulandelelana ngokulandelelana. Xa i-PCB ihanjiswa ukusuka kwiphaneli, ijiyometri kufuneka yandise ngaphandle komda webhodi ukuveza ubhedu. Ijiyometri ye-lamination efanelekileyo inokubonwa ngokujonga imigca ebekekileyo kwimiphetho yeepaneli ezigqityiweyo.

Injongo yolu vavanyo kukuqinisekisa ubungqingqwa bobhedu obusemva kokufakwa kunye nobubanzi kumaleko ngamnye ku lamination. Ukulandela umkhondo kovavanyo kuya kuba yi-50mil ubude kunye ne-5mil ubukhulu, kwaye kufuneka yongeze ngaphaya komphetho webhodi ukuze ubhedu lubhenceke xa i-PCB ihanjiswa kwipaneli. Umbono wokujonga umkhondo wovavanyo unokulinganiswa ngemicroscope yoviwo. Lo msebenzi ubalulekile kuyilo kunye nejometri eqhutywa yimpedance.

Qaphela: Imigca ebanjiweyo kunye noololiwe bovavanyo akufuneki ukuba uqhagamshelwe nakweyiphi na indawo efana nenqwelomoya yamandla okanye izinto zobhedu zepoligoni.
