Best Technology ndeimwe yakanakisisa pcb vagadziri uye akadhindwa redunhu bhodhi vatengesi mu China
Kana zvasvika pakugadzirwa kweakadhindwa edunhu mabhodhi (PCBs) uye zvimwe zvinhu zvemagetsi, nzira mbiri dzinowanzo shandiswa laser stencils uye etching stencils. Nepo ese mastencil achishandira chinangwa chekugadzira chaiwo mapatani, maitiro avo ekugadzira uye mashandisirwo anosiyana zvakanyanya. Muchikamu chino, tichatsanangura mutsauko pakati pelaser stencils uye etching stencils.
Chii chinonzi kemikari etching stencil?
Chemical etching inzira inobvisa yekugadzira iyo inosanganisira kushandisa makemikari kurapwa kusarudza kubvisa zvinhu kubva kune substrates. Inoshandiswa zvakanyanya mukugadzirwa kweakadhindwa edunhu mabhodhi (PCBs) uye inoshandiswawo kugadzira stencils. Iyo etching process ye stencils inowanzo sanganisira kuisa stencil paPCB, kuchenesa zvese stencil nebhodhi, uye kudzokorora nhanho idzi kusvika mhedzisiro yaunoda yawanikwa. Iyi iterative process inogona kutora nguva, ichiita kuti ive imwe yeanonyanya kushanda-yakawanda maficha ekugadzira ehunyanzvi emagetsi mabhodhi, madiki-magungano, uye edunhu mabhodhi. Kuti vakunde zvipingamupinyi zvine chekuita nekucheka kwechinyakare, vamwe vagadziri vatanga kutora stencils-akacheka seimwe nzira.
Sei kushandisa etching stencil?
Etching stencils ane zvinotevera zvinocherechedzwa hunhu.
l Mutengo-Kubudirira:
Maitiro ekugadzira etching stencils anowanzo ratidza kuti inodhura-inoshanda kana ichienzaniswa nelaser stencils.
l Kunyatsorongeka:
Kunyange isiri kuwana nhanho imwechete yekurongeka seye laser stencils, etching stencils ichiri kupa huchokwadi hunogutsa kune akasiyana PCB application.
l Kuchinjika:
Etching stencils inogona kugadziridzwa zviri nyore kana kugadziridzwa kuti igadzirise dhizaini shanduko, ichiita kuti inyanyokodzera prototyping uye diki-chikero kugadzirwa.
Etching stencils anowanzo shandirwa mu-buri-hole tekinoroji (THT) maitiro uye akanyatso kuenderana nezvikamu zvinoda madhipoziti makuru e solder paste. Ivo vanowana kukodzera mumashandisirwo ane yakaderera chikamu densities apo mutengo-kubudirira kunotora zvakakosha.
Chii chinonzi Laser stencil?
Laser stencils, inozivikanwawo semadhijitari stencils, inzira yemazuvano yekugadzira inobvisa inoshandisa lasers inodzorwa nekombuta kunyatsocheka zvinhu kuita maumbirwo chaiwo uye mapatani. Iyi tekinoroji yakabuda muchikamu chekugadzira kutenderera 2010-2012, ichiita kuti ive nyowani muindasitiri.
Kunyangwe iri budiriro ichangoburwa, laser stencils inopa akati wandei mabhenefiti pamusoro pechinyakare kemikari etching stencils. Vagadziri vanogona kubatsirwa nekuderedzwa nguva uye zvinhu zvinodiwa pakugadzira stencils vachishandisa nzira iyi. Uyezve, ma-laser-cut stencils anopa kuwedzera kwakaringana zvichienzaniswa neavo emakemikari etching vamwe.
Zvakanakira kushandisa laser stencil
Laser stencils ane zvinotevera zvinosiyanisa hunhu.
l Precision Yomuenzaniso
Iko kushandiswa kwelaser yekucheka tekinoroji kunogonesa kugadzirwa kweakaomesesa uye akakwenenzverwa mapatani, kuve nechokwadi chakanyanya kurongeka mune solder paste deposition paPCBs.
l Versatility
Laser stencils inopa isingashande kugadzirisa uye kugadzirisa sarudzo kuti isangane neyakagadzirirwa dhizaini, ichiita kuti ive yakanyatsokodzera kune yakafara dhizaini yePCB application.
l Durability
Aya stencils anonyanya kugadzirwa kubva premium-giredhi Stainless simbi, achivapa kusimba kwakasiyana uye hupenyu hurefu, nekudaro achibvumira kushandiswa kwakawanda.
Laser stencils inowana yakawedzera kushanda mune yepamusoro mount tekinoroji (SMT) maitiro, uko kwakaringana solder paste deposition inoita basa rakakosha. Kushandiswa kwavo kunonyanya kubatsira kune yakakwirira-density PCBs, yakanaka-pitch zvikamu, uye yakaoma kutenderera.
Misiyano pakati peetching stencil uye laser stencil
Misiyano pakati pelaser stencils uye etching stencils inogona kupfupikiswa seinotevera:
1. Manufacturing process:
Laser stencils inogadzirwa kuburikidza nekucheka laser, nepo etching stencils inounzwa kuti ibudirire kuburikidza nemakemikari etching.
2. Kururamisa:
Laser stencils inopa kurongeka kwepamusoro, hushoma ndeye 0.01mm, ichivapa yakanakira yeakanaka-pitch zvikamu uye yakakwirira-density PCB. Kusiyana neizvi, etching stencils inopa kurongeka kwakaringana kune maapplication ane zvishoma zvinoomesesa zvinodiwa.
3. Zvinhu uye Kusimba:
Laser stencils anonyanya kugadzirwa kubva simbi isina tsvina, achivimbisa kusimba kwekushandisa kwakawanda. Sezvineiwo, etching stencils anonyanya kugadzirwa kubva kundarira kana nickel, iyo inogona kunge isina mwero wakafanana wekusimba.
4. Zvikumbiro:
Laser stencils inokunda muSMT maitiro anosanganisira akaomarara kutenderera, nepo etching stencils achiwana kushandiswa kwakanyanya muTHT maitiro uye maapplication anoda akakura solder paste deposits.
Sarudzo pakati pelaser stencils uye etching stencils pakupedzisira inotsamira pane izvo zvinodiwa zvePCB kugadzira maitiro. Mapurojekiti anoda kurongeka kwepamusoro, zvikamu zvakanaka-kudzika, uye kutenderera kwakaoma kwaizobatsirika kubva mukushandiswa kwelaser stencils. Sezvineiwo, kana mutengo-kushanda, kuchinjika, uye kuenderana neakakura solder paste deposits zvichitora pamberi, etching stencils inopa mhinduro inoshanda.
