Elinye lamaphutha avame kakhulu ukwenziwa phakathi PCB Ukukhiqiza kungukuhleleka okungafanele kwezikhundla, okungadala ukuthi yonke inqubo yehluleke. Inqubo yenhlangano ye-PCB ingasebenza kusuka endaweni yokubuka kagesi, noma ngabe kuhlolwa ugesi. Ekuklanyeni, ukuhleleka kwendiza nongqimba lwesiginali nebanga eliphakathi kwezendlalelo eziseduze kubalulekile.

Ukuze kuqinisekiswe ukuthi ulwazi lokukhiqiza luyadingeka ukwenza ukuhlolwa okubonakalayo kokucubungula ungqimba, abaklami be-PCB badinga ukuklama izici zethusi ezifanele kudatha yokukhiqiza, okungukuthi, ukufeza ukuhleleka okufanele kwe-cascade. Lezi zici zethusi zihlinzeka ngomshini wokuhlola izingxenye zokugcina, uma kwenziwa ukuhlolwa kwangaphakathi kwe-Q & A, okuhlanzwa kuze kufike esikhungweni sokukhiqiza.

Ukuqashelwa kwesendlalelo?

Umsebenzi wokuqala wethusi ongezwe kusendlalelo ngasinye ukukhomba ukuhleleka kwesendlalelo okuhlobene nazo zonke ezinye izingqimba. Isendlalelo ngasinye sithola inombolo yesendlalelo eboshwe ngqo ethusi, okukhombisa ukuthi ikuphi lapho kuqhuma khona, futhi inombolo yesendlalelo kufanele ifakwe ngaphakathi kwendawo yepuleti eliqediwe. Izinhla kufanele zitholakale eduze komphetho webhodi ukuze zingaphazamisi izici zikagesi zesifunda. Kungathatha ukwakheka kwenombolo eyodwa kusendlalelo ngasinye. Kepha izinombolo kungenzeka zinganqwabeki. Lapho wonke amashadi wokuhlola efakwa, kufanele abonakale ngokusobala lapho ebukwa kusuka phezulu phansi.

Izendlalelo zivame ukufakwa emabhokisini angunxande ukuze kube lula ukubona. Susa imaski yokushisela nomsebenzi wesikrini endaweni ezungeze izingqimba ukwenza lula ukubuka izingqimba nge-PCB ephelele ngomthombo wokukhanya wokuhlola obekwe ngemuva kwenhlangano. Izinhla azikwazi ukuxhumeka kunoma iyiphi ungqimba emsebenzini wethusi, njengaleyo yamandla noma i-polygon.

Izitaki ze-PCB yizici zethusi emaphethelweni e-PCB ukwenza lula ukuhlolwa okubonakalayo kokulandelana okulandelanayo. Lapho i-PCB isuswa kuphaneli, i-geometry kufanele inwebeke ngaphandle komphetho webhodi ukuveza ithusi. I-geometry ye-lamination efanele ingabonakala ngokubheka imivimbo embondelene emaphethelweni wamapaneli aqediwe.

Inhloso yethrekhi yokuhlola ukuqinisekisa ukushuba nobubanzi bethusi obuthunyelwe ngemuva kusendlalelo ngasinye ku-lamination. Ukulandelwa kokuhlolwa kuzoba ngu-50mil ubude no-5mil ubukhulu, futhi kufanele kudlulele ngaphesheya komphetho webhodi ukuze ithusi livezwe lapho i-PCB isuswa kuphaneli. Ukubukwa komphetho wendlela yokuhlola kungalinganiswa ngesibonakhulu sokuhlola. Lo msebenzi ubaluleke kakhulu ekwakhiweni nge-geometry eqhutshwa yimpedance.

Usayizi womugqa nomkhondo wokuhlola udwetshiwe kusendlalelo sefilimu

Qaphela: Imivimbo emile kanye nojantshi wokuhlola akufanele ixhunywe kunoma iyiphi indawo enjengendiza yamandla noma izici zethusi ze-polygon.
