Iindleko zokwenziwa kwebhodi yesekethe ibe yeyona nto ixhalabisayo kuzo zonke iinjineli ze-elektroniki, zifuna ukuqonda eyona nzuzo iphezulu yeemveliso zabo ngeyona ndleko iphantsi.Noko ke, yintoni kanye echaphazela ixabiso lemveliso yebhodi yesekethe? Apha, uya Yazi zonke izinto ezinokuthi zongeze iindleko zePCB yakho.
Isizathu esisisiseko esenza iindleko zePCB
1) Ubungakanani bePCB kunye nobungakanani
Kulula ukuqonda ukuba ubungakanani kunye nobungakanani buyakuchaphazela ixabiso le-PCB, ubungakanani kunye nobungakanani buya kusebenzisa izixhobo ezininzi.
2) iintlobo zezinto ezisetyenzisiweyo ze-substrate
Ezinye izixhobo ezikhethekileyo ezisetyenziswa kwindawo ethile yokusebenza zinokubiza kakhulu kunezixhobo eziqhelekileyo.Ukwenziwa kweeBhodi zeSekethe eziShicileleyo kuxhomekeke kwizinto ezininzi ezisekwe kwisicelo, ezilawulwa ikakhulu ngamaza kunye nesantya sokusebenza, kunye nobona bushushu buphezulu bokusebenza.
3) Inani leeleya
iileya ezininzi ziguqulela kwiindleko ezongezelelweyo ngenxa yamanyathelo amaninzi emveliso, izinto ezininzi, kunye nexesha elongezelelweyo lokuvelisa.
4) Ukuntsokotha kwePCB
PCB ukuntsokotha kuxhomekeke kwinani umaleko kunye nenani vias kwi umaleko ngamnye, njengoko oku kuchaza iiyantlukwano umaleko apho vias iqala kwaye ayeke, efuna kakhulu lamination kunye nokugrumba amanyathelo kwinkqubo yokuvelisa PCB.Abavelisi bachaza inkqubo yokuthambisa njengokucinezela iileya ezimbini zobhedu kunye ne-dielectrics phakathi kweeleya zobhedu ezikufutshane zisebenzisa ubushushu kunye noxinzelelo ukwenza i-laminate yePCB eninzi.
Izinto zexabiso ezivela kwiimfuno zemveliso pf PCB ngokwayo
1. Umkhondo kunye ne-gap geometry-i-thinner ibiza kakhulu.
2. Ukulawulwa kwe-impedance-inkqubo eyongezelelweyo amanyathelo anyusa iindleko.
3. Ubungakanani kunye nokubalwa kwemingxuma-imingxuma engaphezulu kunye nee-diameter ezincinci zokuqhuba iindleko ukuya phezulu.
4. Iplagi okanye i-vias egcwalisiweyo kwaye ingaba zigqunywe ngobhedu—amanyathelo enkqubo eyongezelelweyo anyusa iindleko.
5. Ubunzima bobhedu kwiileyile-ubukhulu obuphezulu buthetha iindleko eziphezulu.
6. Ukugqitywa komphezulu, ukusetyenziswa kwegolide kunye nobukhulu bayo-Imathiriyeli eyongezelelweyo kunye namanyathelo enkqubo yonyusa iindleko.
7. Ukunyamezela—ukunyamezelana kuyabiza.
Ezinye izinto eziphembelela iindleko zePCB
Ezi zinto zincinci zeendleko ezibandakanya udidi lwe-III zixhomekeke kuzo zombini, umenzi kunye nokusetyenziswa kwe-PCB.Ubukhulu becala zibandakanya:
1. Ubukhulu be-NPCB.
2.Unyango oluhlukeneyo lomphezulu.
3. ukugquma abantu abadala.
4. Ukushicilelwa kwentsomi.
5. Iklasi yentsebenzo yePCB (IPC Class II/III njl.).
6. PCB contour-ingakumbi z-axis umzila.
7. Icala okanye i-edge plating.
I-PCBA iya kukunika amacebiso angcono ngokufanelekileyo ukukunceda ukuba uhlise iindleko zeebhodi ze-PCB,
