Uqinisekisa njani kwaye uhlalutye indibano yePCB yonikezelo lwamandla ombane omfutshane?

Xa ujongene nendibano ye-PCB, eyona nto inzima ukuqikelela nokusombulula ingxaki yombane omfutshane.Ngokukodwa xa ibhodi inzima ngakumbi kwaye iimodyuli zesekethe ezahlukahlukeneyo zanda, ingxaki yombane wesiphaluka esifutshaneIndibano yePCBkunzima ukulawula.

Indlela yokuhlalutya ubushushu

UhlalutyoIntshayelelo:

1. Ngokubanzi, ukuba ibhodi ayifutshane-ijikelezwe ngetoti, umzekelo, i-chip yaphukile okanye i-capacitor yaphukile, ukuchasana kwe-GND ngokuqhelekileyo akukho 0Ω, ngaphezulu okanye ngaphantsi, kuya kubakho ezimbalwa Ω okanye ezimbalwa zeshumi. kwe Ω.Usebenzisa eli nqaku, ungakhangela ngokukhawuleza.

2. Sebenzisa umbane olawulwa ngokuthe ngqo ngoku.Lungisa i-voltage yonikezelo lwamandla kwi-voltage ye-short-circuit power supply (3.3V i-short-circuit ukuya kwi-3.3V).Yibeke kwimowudi yokunciphisa yangoku, umlinganiselo wangoku ungamiselwa kwi-500mA, kuxhomekeke kwimeko yokwenyani.

3. Nciphisa unikezelo lombane lweIbhodi yendibano yePCB, qhagamshela kwi-set power supply, kwaye ubone apho ibhodi yesiphaluka ishushu, kwaye apho ishushu ngokuqhelekileyo isiphaluka esifutshane.

4. Ukubona apho bukhoyo ubushushu, ungasebenzisa umfanekiso we-infrared thermal ukujonga.Ukuba awunayo i-infrared thermal imager, ungayibamba ngqo ngezandla zakho kwaye uyive (lumkele ukuba ungazitshisi.

Ukulumkela:

Ukumiselwa komda wangoku womthombo othe ngqo wangoku kufuneka umiselwe ngokweyona meko.Ukuba ukumiselwa komda wangoku kuncinci kakhulu, ubushushu abuyi kubonakala, kwaye akukho ngxaki inokufumaneka.Ukuba isicwangciso somda wangoku sikhulu kakhulu, iingcingo zobhedu kwi-PCB zinokutshiswa.Ungacotha uhlengahlengiso lwangoku ukusuka kwincinci ukuya enkulu de ube uyazi apho ingxaki ilele.

Ngelizwi nje, Kwinkqubo yokuphelisa isiphaluka esifutshane sendibano yombane yePCB, kufuneka sinikele ingqalelo ukufumanisa nokusombulula ingxaki ngokufanelekileyo.

PCBFuture inokuqala kwiukuveliswa kwebhodi yesekethe eprintiweyo, ukuya kubonelelo lwamacandelo kunye nokudibanisa.Siyavuya ukubonelela ngeebhodi kunye namacandelo.Emva kokuba imveliso igqityiwe, sinokubonelela ngohlolo lwe-PCB yobungcali ukuqinisekisa umgangatho we-PCB.Ngolwazi oluthe vetshe, nceda u-imeyilele kuservice@pcbfuture.com.
