Graphitization ngokuthi electroplating kwimingxunya okanye imingxunya kumphetho PCB.Sika umda webhodi ukwenza uluhlu lwemingxuma yesiqingatha.Le mingxunya yeehafu yinto esiyibiza ngokuba yistamp hole pads.
1. Ukungalungi kwemingxuma yesitampu
①: Emva kokuba ibhodi yahluliwe, inesimo esifana nesarha.Abanye abantu bayibiza imilo yezinyo lenja.Kulula ukungena kwiqokobhe kwaye ngamanye amaxesha idinga ukunqunyulwa ngesikere.Ngoko ke, kwinkqubo yokuyila, indawo kufuneka igcinwe, kwaye ibhodi iyancipha ngokubanzi.
②: Yandisa iindleko.Ubuncinci bomngxuma wesitampu ngu-1.0MM umngxuma, ngoko lo bukhulu be-1MM bubalwa ebhodini.
2. Indima yemingxuma yesitampu eqhelekileyo
Ngokubanzi, i-PCB yi-V-CUT.Ukuba udibana nebhodi ekhethekileyo okanye ejikelezileyo, kunokwenzeka ukusebenzisa umngxuma wesitampu.Ibhodi kunye nebhodi (okanye ibhodi engenanto) idibene nemingxuma yesitampu, eyona nto idlala indima exhasayo, kwaye ibhodi ayiyi kuhlakazeka.Ukuba i-mold ivuliwe, i-mold ayiyi kudilika..Okuqhelekileyo, zisetyenziselwa ukwenza iimodyuli ezizimeleyo ze-PCB, ezifana ne-Wi-Fi, i-Bluetooth, okanye iimodyuli zebhodi ezingundoqo, ezithi ke zisetyenziswe njengamacandelo azimele abekwe kwenye ibhodi ngexesha lendibano ye-PCB.
3. Isithuba ngokubanzi semingxuma yesitampu
0.55mm~~3.0mm (kuxhomekeke kwimeko, isetyenziswa ngokuqhelekileyo 1.0mm, 1.27mm)
Zeziphi iintlobo eziphambili zemingxuma yesitampu?
- Umngxuma wesiqingatha
- Umngxuma omncinci onesiqingatha sehol
- Imingxuma tangent ukuya emphethweni webhodi
4. Iimfuno zemingxuma yesitampu
Ngokuxhomekeke kwiimfuno kunye nokusetyenziswa kokuphela kwebhodi, kukho iimpawu zoyilo ezifuna ukufezekiswa.Umzekelo:
①Ubungakanani: Kuyacetyiswa ukuba usebenzise obona bukhulu bunokwenzeka.
②Unyango lwangaphandle: Kuxhomekeke ekupheleni kokusetyenziswa kwebhodi, kodwa i-ENIG iyacetyiswa.
③ Uyilo lwepedi ye-OL: Kuyacetyiswa ukuba usebenzise eyona pad inkulu yeOL ngaphezulu nasezantsi.
④ Inani lemingxuma: Kuxhomekeke kuyilo;kunjalo, kuyaziwa ukuba elincinane inani imingxunya, kokukhona nzima inkqubo indibano PCB.
Imingxuma enesiqingatha eplathiweyo iyafumaneka kuzo zombini ii-PCB ezisemgangathweni neziphambili.Kuyilo oluqhelekileyo lwe-PCB, ubuncinci bedayamitha yomngxuma oyi-c yi-1.2 mm.Ukuba ufuna imingxunya emincinci emise okwe-c, umgama omncinci phakathi kwemingxunya emibini ecandiweyo yi-0.55 mm.
Inkqubo yokuVelisa umngxuma wesitampu:
Okokuqala, yenza yonke into efakwe emngxunyeni njengesiqhelo kumda webhodi.Emva koko sebenzisa isixhobo sokusila ukusika umngxuma ube phakathi kunye nobhedu.Ekubeni i-copper inzima kakhulu ukuyigaya kwaye inokubangela ukuba i-drill iphuke, sebenzisa i-drill duty duty drill ngesantya esiphezulu.Oku kubangela umgangatho ogudileyo.Umngxuma ngamnye uthi uhlolwe kwisikhululo esinikezelweyo kwaye ugxothwe xa kukho imfuneko.Oku kuya kwenza umngxuma wesitampu esiwufunayo.
