Graphitization ngokuthi electroplating kwimingxunya okanye imingxunya kumphetho PCB. Sika umda webhodi ukwenza uluhlu lwemingxuma yesiqingatha. Le mingxunya enesiqingatha 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. . Ngokuqhelekileyo, 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 ezinye iimpawu zoyilo ezifuna ukuhlangabezana nazo. 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 lincinci inani lemingxuma, inzima ngakumbi inkqubo yendibano yePCB.
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 iplate emngxunyeni njengesiqhelo kumda webhodi. Emva koko sebenzisa isixhobo sokusila ukusika umngxuma ube phakathi kunye nobhedu. Ekubeni ubhedu kunzima kakhulu ukugawula kwaye kunokubangela 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.
