Indlela yokukhetha umatshini wokusika wepcb ofanelekileyo.

Abavelisi abaninzi bemveliso ye-elektroniki bavelisa iibhodi ze-PCB, kwaye baqalise ukukhetha ukusebenzisa abasiki be-pcb ngenxa yeemfuno zokwandisa imveliso kunye nokuphucula umgangatho wemveliso.Kodwa abantu abaninzi abazi ukuba bakhethe njani aumatshini wokusika ibhodi pcb, ucinga ukuba kungakhathaliseki ukuba yintoni umatshini unokwahlula zonke iibhodi zePCB.Enyanisweni, iibhodi PCB zahlukile, iimveliso ezenziwe umthengi ngamnye ezahlukeneyo, kunye neentlobo zeebhodi PCB nazo ezahlukeneyo.Ngoko ke, kuyimfuneko ukukhetha ezahlukeneyoumatshini wokucocaiibhodi PCB ezahlukeneyo., Eyokuqala yibhodi yePCB enamalungu.Xa amacandelo angekho phezulu kwaye ibhodi yePCB ayinkulu, kuyacetyiswa ukuba ukhethe uhlobo lwemelapcb umatshini wokusika.Ukuguquguquka kwayo kunamandla kakhulu.Emva kokuba iibhodi zePCB ezininzi ezidityanisiweyo zithengisiwe, kulula ukonakalisa isekethe okanye ukwaphula iinxalenye ze-elektroniki.Ukunyathela, imela ephezulu ejikelezayo ihamba ngokuthe tye ukuya kwindawo emiselweyo, oko kukuthi, ibhodi ye-PCB iyasikwa kwaye yahlulwe, kwaye ukusika akuwi ngocingo, ukusika kusicaba, kwaye akukho burr.Iqonga lokuhambisa lingafakelwa ukuququzelela ukuhanjiswa ngokuzenzekelayo kwebhodi yePCB esikiweyo, ngaloo ndlela kuncitshiswe uxinzelelo, kuthintelwe ukuqhekeka kwe-solder kunye nokuqhekeka kwamalungu, kunye nokuphucula ukusebenza kakuhle kwemveliso kunye nomgangatho.

Eyesibini yibhodi encinane.Ibhodi yePCB ilula kuyilo, kodwa ibhityile kakhulu.Kucetyiswa ukuba ukhethe i-guillotinepcb umsiki.Umatshini wokuqhawula uhlobo lwe-guillotine uthatha i-gas-electric light-weight yamva nje ukuyila, enokugqiba i-stroke yokusika ngaphandle koxinzelelo lwe-shear ngexesha elinye, ngokukodwa ngokufanelekileyo ukusika ngokuchanekileyo i-SMD okanye iiplate ezincinci;ngaphandle kwamaza isaphetha kunye micro-neentanda eziveliswe xa uhlobo imela setyhula ukwahlula, sebenzisa Wedge-ezimilise isixhobo linear ukwahlula kunciphisa uxinzelelo lokucheba, ukuze amacandelo anovakalelo SMD, nkqu capacitors, abachaphazeleki, kunye nemingcipheko enokubakho umgangatho imveliso incitshisiwe.Ukongeza, kukho ezo zingaqhelekanga, umngxuma wesitampu, iibhodi zePCB ezibhlohliweyo, kuyacetyiswa ukuba ukhethe ijika.isahluli sepcb.Umhlukanisi wegophe ukwabizwa ngokuba ngumsiki wohlobo lokusila.Ikakhulu sisixhobo esisebenzisa isantya esiphezulu sokusika umsiki wokusila ukwahlula iPCB enamacandelo amaninzi ngokwendlela ecwangciswe kwangaphambili, ibuyisela ukwaphuka kwezandla okanye iziphene zokusika.V-CUTokanye I-PUSH, ukusika Ukuchaneka okuphezulu kunye nokuchaneka, ubomi benkonzo ende, umgangatho omhle wokusika, akukho thuli, akukho burrs, uxinzelelo oluphantsi, ukhuseleko kunye nokulula, ukuphucula umgangatho wemveliso kunye nokunciphisa izinga le-scrap.Isetyenziswa ikakhulu ukwahlula iibhodi PCB ezingaqhelekanga, iibhodi umngxuma isitampu, kunye neebhodi point yokuqhagamshela.Uxinzelelo lokusika luncinci, malunga ne-1/10 yohlobo lwe-stamping kunye ne-1/100 yohlobo lokuqhawula ngesandla, ukwenzela ukukhusela ii-chips ezifana ne-ceramic capacitors ukuba zingonakaliswe ngexesha lokusika;ziphephe iintanda zenkcenkce kunye nomonakalo wecandelo obangelwa kukusongwa ngesandla.
