Best Technology yenye abavelisi pcb ilungileyo eprintiweyo ababoneleli ngebhodi yesekethe e China
Xa kuziwa kukwenziwa kweebhodi zesekethe eziprintiweyo (PCBs) kunye namanye amacandelo e-elektroniki, iindlela ezimbini eziqhele ukuqeshwa ziistencil zelaser kunye ne-etching stencils. Ngelixa zombini iistencil zisebenzela injongo yokudala iipatheni ezichanekileyo, iinkqubo zabo zokuvelisa kunye nokusetyenziswa kwazo ziyahluka kakhulu. Kweli nqaku, siza kuchaza umahluko phakathi kwe-laser stencils kunye ne-etching stencils.
Yintoni i-chemical etching stencil?
Ukufakwa kwemichiza bubuchule bokuvelisa obuthathayo obubandakanya ukusebenzisa unyango lwekhemikhali ukususa ngokukhethayo imathiriyeli kwi-substrates. Isetyenziswa ngokubanzi kwimveliso yeebhodi zesekethe eziprintiweyo (PCBs) kwaye ikwaqeshelwe ukwenza iistencil. Inkqubo yokubhala i-stencil ibandakanya ukufaka i-stencil kwi-PCB, ukucoca zombini i-stencil kunye nebhodi, kunye nokuphinda la manyathelo kude kube kuphunyeziwe umphumo ofunekayo. Le nkqubo yophindaphindo inokuthatha ixesha, iyenze ibe yenye yezinto ezifuna umsebenzi onzima wokwenza iibhodi ezikhethekileyo zombane, iindibano ezincinane, kunye neebhodi zesekethe. Ukoyisa imiceli mngeni eyayanyaniswa ne-etching yemveli, abanye abavelisi baqalisile ukwamkela iistencil zokusikwa kwelaser njengenye indlela.
Kutheni usebenzisa i-etching stencil?
Iistencil zokubhala zinezi mpawu zilandelayo.
l Iindleko-Ngempumelelo:
Inkqubo yokwenziwa kwee-stencils etching ngokubanzi ingqina ukuba inexabiso elithe kratya xa ithelekiswa neestencil zelaser.
l Ukuchaneka okwaneleyo:
Ngelixa ungafikeleli kwinqanaba elifanayo lokuchaneka njenge-laser stencils, iistencil zokuchopha zisabonelela ngokuchaneka okwanelisayo kwezicelo ezahlukeneyo zePCB.
l Ukuba bhetyebhetye:
I-stencil yokufaka i-stencil inokuguqulwa ngokulula okanye ilungelelaniswe ukulungiselela ukuguqulwa koyilo, ibenze bafaneleke ngokukodwa kwiprototyping kunye nemveliso encinci.
I-stencils etching zidla ngokusetyenziswa kwiinkqubo zetekhnoloji ye- through-hole (THT) kwaye zifaneleke kakuhle kumacandelo afuna iidipozithi ezinkulu ze-solder paste. Bafumana ukufaneleka kwizicelo ezinoxinano lwamacandelo aphantsi apho ukusebenza kakuhle kweendleko kuthathwa ngokubaluleka okukhulu.
Yintoni iLaser stencil?
Iistencil zeLaser, ezikwabizwa ngokuba zii-digital stencils, luhlobo lwangoku lokwenziwa kwe-subtractive esebenzisa iilaser ezilawulwa yikhompyuter ukusika ngokuchanekileyo izixhobo zibe ziimilo ezithile kunye neepateni. Le teknoloji yavela kwicandelo lemveliso malunga ne-2010-2012, iyenza ibe yinto entsha kwishishini.
Ngaphandle kophuhliso lwakutsha nje, iistencil zelaser zibonelela ngeenzuzo ezininzi ngaphezulu kweestencil zekhemikhali zokuchwela. Abavelisi banokuzuza ngokuncitshiswa kwexesha kunye neemfuno zezinto eziphathekayo xa bedala i-stencils usebenzisa le ndlela. Ngaphezu koko, i-laser-cut stencils ibonelela ngokuchaneka okuphuculweyo xa kuthelekiswa noogxa bawo beekhemikhali.
Iinzuzo zokusebenzisa i-laser stencil
Iistencil zeLaser zinezi mpawu zilandelayo zokwahlula.
l Ukuchaneka okungumzekelo
Ukuqeshwa kwetekhnoloji yokusika i-laser yenza ukuba kudalwe iipateni ezintsonkothileyo nezisulungekisiweyo, ziqinisekisa eyona nto ichanekileyo kwi-solder paste deposition kwi-PCBs.
l Ukuguquguquka
Iistencil zeLaser zibonelela ngokwenziwa ngokwezifiso kunye neenketho zokuhlengahlengisa ukuhlangabezana neemfuno ezithile zoyilo, zizenza zilungele uthotho lwezicelo zePCB.
l Ukuqina
Ezi stencil ziyilwe ubukhulu becala ukusuka kwi-premium-grade stainless steel, ezenza ukuba zibe nokuqina okukhethekileyo kunye nobomi obude, ngaloo ndlela zivumela ukusetyenziswa okuninzi.
Iistencil zeLaser zifumana ukusetyenziswa okubanzi kwiinkqubo zeteknoloji ye-surface Mount (SMT), apho ukubekwa kwe-solder paste echanekileyo kudlala indima ebalulekileyo. Ukusetyenziswa kwazo kuluncedo ngakumbi kwiiPCB ezinoxinano oluphezulu, izinto ezinomgangatho ophantsi, kunye nokujikeleza okuntsonkothileyo.
Umahluko phakathi kwe-etching stencil kunye ne-laser stencil
Umahluko phakathi kweestencil zelaser kunye ne-etching stencils unokushwankathelwa ngolu hlobo lulandelayo:
1. Inkqubo yokuVelisa:
Iistencil zeLaser ziveliswa ngokusikwa kwelaser, ngelixa i-etching stencils ziziswa ngeziqhamo ngokufakwa kweekhemikhali.
2. Ukuchaneka:
Iistencil zeLaser zibonelela ngokuchaneka okuphezulu, ubuncinci yi-0.01mm, zibenza zibe zilungele iinxalenye zepitch kunye neePCB ezinoxinano oluphezulu. Ngokwahlukileyo, ii-stencils zokuchopha zihambisa ukuchaneka okwaneleyo kwizicelo ezineemfuno ezingqongqo.
3. Izinto eziphathekayo kunye noKuhlala ixesha elide:
Iistencil zeLaser ziyilwe ngokuyintloko ngentsimbi engatyiwa, eqinisekisa ukuqina kokusetyenziswa okuninzi. Kwelinye icala, iistencil zokuchopha zenziwa ubukhulu becala ngobhedu okanye i-nickel, ezinokungabi nanqanaba elifanayo lokuqina.
4. Usetyenziso:
Iistencil zeLaser zigqwesa kwiinkqubo ze-SMT ezibandakanya ukujikeleza okuntsonkothileyo, ngelixa i-etching stencils ifumana ukusetyenziswa okukhulu kwiinkqubo zeTHT kunye nezicelo ezifuna iidiphozithi ezinkulu zokuncamathisela.
Ukhetho phakathi kweestencil ze-laser kunye ne-etching stencil ekugqibeleni luxhomekeke kwiimfuno ezithile zenkqubo yokwenziwa kwePCB. Iiprojekthi ezifuna ukuchaneka okuphezulu, izakhi zepitch, kunye neesekethe ezintsonkothileyo ziya kuxhamla ekusetyenzisweni kweestencil zelaser. Ngokwahlukileyo, ukuba ukuphumelela kweendleko, ukuguquguquka, kunye nokuhambelana nediphozithi enkulu ye-solder paste kuthatha indawo yokuqala, i-stencils etching inika isisombululo esisebenzayo.
