Ibhodi yesekethe eprintiweyo
Iibhodi zesekethe eziprintiweyo, ezikwabizwa ngokuba ziibhodi zesekethe eziprintiweyo, ziluqhagamshelo lombane kumacandelo e-elektroniki.Iibhodi zesekethe eziprintiweyo zidla ngokubizwa ngokuba yi “PCB” kune “PCB board”.Sele kuphuhliso iminyaka engaphezu kwe-100;Uyilo lwayo ikakhulu...Funda ngokugqithisileyo -
Yintoni umngxuma wesixhobo sePCB?
Umngxuma wezixhobo zePCB ubhekisa ekumiseleni indawo ethile yePCB ngomngxuma kwinkqubo yoyilo lwePCB, ebaluleke kakhulu kwinkqubo yoyilo lwePCB.Umsebenzi wokufumana umngxuma yi-data processing datum xa ibhodi yesekethe eprintiweyo yenziwe.Indlela yokubeka umngxuma we-PCB...Funda ngokugqithisileyo -
Inkqubo yoKwemba ngasemva yePCB
Yintoni ukubhola ngasemva?Ukwemba ngasemva luhlobo olukhethekileyo lokomba umngxuma onzulu.Kwimveliso yeebhodi ezininzi, ezifana neebhodi ze-12-layer, kufuneka sidibanise umgca wokuqala kwinqanaba lesithoba.Ngesiqhelo, sigrumba umngxuma (umatshini omnye) kwaye sitshone ubhedu. Ngale ndlela, ...Funda ngokugqithisileyo -
Amanqaku oYilo lweBhodi yeSekethe yePCB
Ngaba i-PCB igqibekile xa uyilo lugqityiwe kwaye akukho ngxaki zifumanekayo ngoqhagamshelo kunye nezithuba?Kakade ke, impendulo nguhayi.Uninzi lwabasaqalayo, kuquka iinjineli ezinamava, ngenxa yexesha elilinganiselweyo okanye ukuphelelwa ngumonde okanye ukuzithemba kakhulu, badla ngokungxama, bangahoyi...Funda ngokugqithisileyo -
Kutheni le nto iMultilayer PCB iZimaleko?
Ibhodi yePCB inomaleko omnye, iileya ezimbini kunye neengqimba ezininzi, phakathi kwazo akukho mda kwinani leengqimba zebhodi ye-multilayer.Okwangoku, kukho ngaphezu kwe-100 iileya ze-PCB, kwaye i-multilayer PCB eqhelekileyo inamaleko amane kunye nemigangatho emithandathu.Ke kutheni abantu besithi, "Kutheni iPCB i-multilayers ...Funda ngokugqithisileyo -
Ukunyuka kobushushu beBhodi yeSekethe eShicileleyo
Isizathu esithe ngqo sokunyuka kobushushu be-PCB kungenxa yobukho bezixhobo zokuchitha amandla esekethe, izixhobo zombane zinemigangatho eyahlukeneyo yokuchitha amandla, kwaye ubushushu bobushushu buhluka ngokuchithwa kwamandla.Iziganeko ezi-2 zokunyuka kweqondo lokushisa kwi-PCB: (1) ukunyuka kwamaqondo obushushu okanye...Funda ngokugqithisileyo -

Iindlela ezininzi zoNyango lwe-Multilayers Pcb Surface
Umgangatho womoya oshushu usetyenziswa kumphezulu we-PCB etyhidiweyo yesoda yetoti etyhidiweyo kunye nenkqubo yomgangatho womoya ofudumeleyo (ukuvuthela tyaba).Ukwenza ukuba yenze i-oxidation resistant coating inokubonelela nge-weldability elungileyo.Isoda yomoya oshushu kunye nobhedu zenza ikhompawundi ye-copper-sikkim ekudibaneni kweendlela, ezinobunzima...Funda ngokugqithisileyo -
Amanqaku obhedu Shicilela ibhodi yesekethe
I-CCL (i-Copper Clad Laminate) kukuba ithathe indawo esecaleni kwi-PCB njengenqanaba lereferensi, uze uyigcwalise ngobhedu oluqinileyo, olukwabizwa ngokuba kukugalelwa kobhedu.Ukubaluleka kwe-CCL njengoko kungezantsi: ukunciphisa i-impedance yomhlaba kunye nokuphucula amandla okuchasana nokuphazamiseka ukunciphisa ukuhla kwamandla ombane kunye nokuphucula amandla ...Funda ngokugqithisileyo -
Yintoni uBudlelwane phakathi kwePCB kunye neSekethe eDityanisiweyo?
Kwinkqubo yokufunda i-electronics, sihlala siqaphela ibhodi yesekethe eprintiweyo (PCB) kunye nesekethe edibeneyo (IC), abantu abaninzi "badidekile" malunga nezi ngcamango zimbini.Ngapha koko, azintsonkothanga kangako, namhlanje siza kucacisa umahluko phakathi kwePCB kunye nesengqa esidibeneyo...Funda ngokugqithisileyo -
Umthamo wokuthwala wePCB
Umthamo wokuthwala we-PCB uxhomekeke kwizinto ezilandelayo: ububanzi bomgca, ubukhulu bomgca (ubunzima bobhedu), ukunyuka kweqondo lokushisa elivumelekileyo.Njengoko sonke sisazi, okukhona umkhondo wePCB ubanzi, kokukhona umthamo wokuthwala wangoku.Ukucinga ukuba phantsi kweemeko ezifanayo, umgca we-10 we-MIL ca ...Funda ngokugqithisileyo -
Izinto eziqhelekileyo zePCB
I-PCB kufuneka ikwazi ukumelana nomlilo kwaye ayinakutshisa kwiqondo lobushushu elithile, ukuze ithambe kuphela.Iqondo lobushushu ngeli xesha libizwa ngokuba liqondo lobushushu beglasi (inqaku leTG), elinxulumene nozinzo lobungakanani bePCB.Zeziphi i-TG ephezulu ye-PCB kunye nezibonelelo zokusebenzisa i-TG PCB ephezulu?Nini ...Funda ngokugqithisileyo
