Malunga noYilo lweBhodi yePCB yethu

Xa siyila ibhodi ye-PCB, sikwanayo nemigaqo yemithetho: okokuqala, cwangcisa izikhundla eziphambili zecandelo ngokwenkqubo yomqondiso, kwaye emva koko ulandele "isekethe kuqala nzima kwaye kulula, ivolumu yecandelo ukusuka kwinkulu ukuya encinci, umqondiso onamandla kunye ukwahlukana komqondiso obuthathaka, ophezulu kunye nophantsi.Imiqondiso eyahlukeneyo, imiqondiso eyahlukeneyo ye-analog kunye nedijithali, zama ukwenza iingcingo zibe mfutshane kangangoko, kwaye wenze uyilo lube nengqiqo kangangoko”;ingqwalasela eyodwa kufuneka ihlawulwe kwindawo eyahlukileyo "yomhlaba wesignali" kunye "nomhlaba wamandla";oku ikakhulu kukuthintela umhlaba wamandla Umgca ngamanye amaxesha unomsinga omkhulu odlula kuwo.Ukuba lo mbane ungeniswa kwi-terminal ye-signal, iya kubonakaliswa kwi-terminal ephumayo nge-chip, ngaloo ndlela ichaphazela ukusebenza kokulawulwa kombane wombane wokutshintsha umbane.
Emva koko, indawo yokulungelelanisa kunye nolwalathiso lwe-wiring yamacandelo kufuneka luhambelane ngokusemandleni kunye ne-wiring ye-diagram yesiphaluka, eya kuba luncedo kakhulu ekugcinweni nasekuhlolweni kamva.
Ucingo oluphantsi kufuneka lube mfutshane kwaye lube banzi kangangoko kunokwenzeka, kwaye ucingo olushicilelweyo oludlula kumbane otshintshayo kufuneka lwandiswe kangangoko kunokwenzeka.Ngokuqhelekileyo, sinomgaqo-siseko xa i-wiring, ucingo lomhlaba lubanzi kakhulu, ucingo lwamandla lusesibini, kwaye ucingo lwesignali luncinci.
Nciphisa iluphu yengxelo, igalelo kunye nemveliso yokulungiswa kwendawo yeluphu yeluphu kangangoko, le njongo kukunciphisa uphazamiseko lwengxolo yonikezelo lombane lokutshintsha.

One-stop Solution

Izixhobo ze-inductive ezifana ne-thermistors kufuneka zigcinwe kude kangangoko kunokwenzeka kwimithombo yobushushu okanye izixhobo zesekethe ezibangela ukuphazamiseka.
Umgama odibeneyo phakathi kweetshiphusi ezimbini zomgca kufuneka ube mkhulu kune-2mm, kwaye umgama phakathi kwe-chip resistor kunye ne-chip capacitor kufuneka ube mkhulu kune-0.7mm.
I-capacitor yokucoca igalelo kufuneka ibekwe ngokusondeleyo kangangoko kunokwenzeka kumgca ofuna ukuhluzwa.
Kuyilo lwebhodi ye-PCB, iingxaki eziqhelekileyo ziyimimiselo yokhuseleko, i-EMC kunye nokuphazamiseka.Ukuze sisombulule ezi ngxaki, kufuneka sinikele ingqalelo kwizinto ezintathu xa kuyilwa: umgama wendawo, umgama we-creepage kunye nomgama wokungena kwe-insulation.Impembelelo.
Umzekelo: Umgama we-Creepage: xa i-input voltage i-50V-250V, i-LN phambi kwe-fuse i-≥2.5mm, xa i-voltage input i-250V-500V, i-LN phambi kwe-fuse ≥5.0mm;ukuchithwa kombane: xa igalelo lombane li-50V-250V, L-N ≥ 1.7mm phambi kwe-fuse, xa i-voltage yegalelo i-250V-500V, L-N ≥ 3.0mm phambi kwe-fuse;akukho mfuneko efunekayo emva kwefuse, kodwa zama ukugcina umgama othile ukuphepha umonakalo omfutshane wesiphaluka kunikezelo lwamandla;icala lokuqala AC ukuya DC inxalenye ≥ 2.0 mm;icala lokuqala DC umhlaba ukuya emhlabeni ≥4.0mm, ezifana necala eliphambili emhlabeni;icala eliphambili ukuya kwicala lesibini ≥6.4mm, njenge-optocoupler, i-Y capacitor kunye nezinye iinxalenye zecandelo, isithuba se-pin singaphantsi okanye silingana ne-6.4mm ukuba ifakwe;i-transformer yamanqanaba amabini ≥6.4mm okanye ngaphezulu, ≥8mm yokufakelwa kokuqinisa.

FAQ

I-Q1: Uqinisekisa njani umgangatho weePCB?
I-A1: Ii-PCB zethu zonke ziyi-100% yovavanyo olubandakanya uvavanyo lwe-Flying Probe, uvavanyo lwe-E okanye i-AOI.

I-Q2: Liliphi ixesha lokukhokela?
I-A2: Iimfuno zesampuli ze-2-4 iintsuku zokusebenza, imveliso yobuninzi idinga iintsuku ezi-7-10 zokusebenza.Kuxhomekeke kwiifayile kunye nobuninzi.

I-Q3: Ndingalifumana ixabiso elifanelekileyo?
A3: Ewe.Ukunceda abathengi balawule iindleko yinto esihlala sizama ukuyenza.Iinjineli zethu ziya kubonelela ngoyilo oluhle kakhulu lokugcina izinto zePCB.
