Indlela yokufumana amanqaku i-V isetyenzisiwe iminyaka emininzi kwimveliso ye- ibhodi yesekethe eprintiweyo (IPCB). Ngeteknoloji yemveliso ye-PCB eguquka ngokukhawuleza, kubalulekile ukuba wazi izikhokelo zamanqaku zePBB zamva nje ekufuneka zilandelwe kunye nendlela ezinokwahluka ngayo kwinto obukade uyisebenzisa ngaphambili.

Inkqubo yokufaka amanqaku ibandakanya iincakuba ezimbini ezijikeleza ngokusondeleyo kwindawo yokuya kwindawo enye njengoko i-PCB ihamba phakathi kweebhleyidi. Inkqubo iphantse yafana nokusika i-pizza kwi-pancake, ukusika i-pizza kwizilayi ezibhityileyo kwaye ngokukhawuleza uhambise imveliso kwinyathelo elilandelayo, elinokuphucula imveliso iyonke. Ke kufuneka uwasebenzise nini amanqaku kwi-PCB yakho? Zeziphi iingxaki ezinokubakho kule nkqubo?

Ibhodi yesekethe eprintiweyo

Nokuba i-PCB yakho isikwere okanye ixande, onke amacala anemigca ethe tye kwaye anganqunyulwa kumatshini we-V-notch. Umbuzo oza kuwubuza ngulo, ngaba ukulungele ukuhlelwa, okanye ngaba zikhona ezinye iindawo ekufuneka ziqwalaselwe? Ukufumana amanqaku okanye ukungafumani manqaku? Nazi izizathu ezimbalwa zokwala ukuphendula.

Inqaku lePCBS licekeceke

Iibhodi zesekethe eziprintiweyo zincinci kune-intshi eyi-0.040 kunzima ukuzitsala ngezizathu ezininzi. Ubuncinci be-0.012 “iyafuneka ukukhusela i-coil emile ngo-V, njengoko (coil) inotshi blade yasekhohlo isetelwe ngaxeshanye notch 0.010” – ubunzulu be-0.012 “kumacala omabini aya kwenza i-0.020″ +/- 0.004 ” net incinci kuno-0.040 ”.

Iibhodi zesekethe eziprintiweyo ezincinci zinokuphambuka kuphela kwizinto eziphathekayo. I-PCBS eguqukayo usebenzisa indlela yekhefu engafakwanga inokushiya imiphetho erhabaxa kwaye ixhome imicu. Ukulawula inkqubo yokufumana amanqaku ngezixhobo ezincinci kunye nokuvumela ukuphazamiseka okubalulekileyo kunzima. Ikhaba libalulekile kuseto lokunyamezelana kobunotshi ukusuka phezulu kuye ezantsi, kwaye kukho uluhlu oluqinileyo lokuchaneka ukuqinisekisa ukuba izinto zobubanzi azophuli ngexesha lendibano. Xa ubunzulu benotshi bungalingani phakathi kwekhohlo nasekunene, inxenye iya kuba nzima ngakumbi ukuyaphula, ishiye imicu kunye nemiphetho yokuqhekeka okunokwenzeka.

I-PCB kuludwe lwamanqaku inamanqaku

Xa kusenziwa ubhalo ngakumbi, kokukhona iiphaneli zoluhlu zinokuba buthathaka, zikhokelela ekuphatheni oku-ethe-ethe, kulungelelwaniso olonakeleyo kunye / okanye kwingxaki.

Icandelo elinamanqaku amancinci

Incinci i-intshi yesikwere sebhodi, kokukhona kunzima ukunqamla. Xa ubungakanani bePCB buncinci, iibhodi ziyatyeba kune-0.062 “kunzima ngakumbi ukwahlulahlula. Ngaphantsi kwe-intshi enye kwicala ngalinye kunokufuna izixhobo ezongezelelweyo ukwahlula iinxalenye.

Inqaku le-PCB inde kakhulu

Iibhodi zesekethe eziprintiweyo ezine-X okanye Y ezinde (i-intshi ezili-12 okanye nangaphezulu) zinokuba buthathaka kwaye zaphuke ngokulula xa zikrobe kakhulu. Ukongeza izinto ezinzima kuluhlu esele lubuthathaka kunokubangela ukuba iiphaneli zaphule ngexesha lokuphatha, lokuhlanganisa, okanye lokuhambisa. Ukuphumeza amanqaku okutsiba okanye ukuhambisa i-tabular kunokuba lukhetho olungcono.

Ipleyiti yokufaka amanqaku

Ukuba ubeka i-PCBS enkulu kune-0.096 intshi ubukhulu, sebenzisa iskimu esifanayo, kunye namacwecwe amabini asika nzulu kumphezulu we-laminate, ushiye i-net ye-0.020 intshi +/- 0.004 intshi. Ngaphezulu kobukhulu, kunzima ukwaphula, kuba ukugoba akwanele. Iibhloko ezijiyileyo zingasebenzisa le ndlela kwiibhodi ezomeleleyo, kodwa ngamanye amaxesha zinokukhokelela kwiingxaki ngobhedu ukuya kumda oshiyekileyo.

Isixhobo sokufaka amanqaku

Kukho izixhobo ezikhoyo zokuncedisa kwisigqibo sePCBS. Nangona kunjalo, kufuneka isetyenziswe ngokuchanekileyo kwaye ibekwe esweni ngokuchaneka ukuthintela ukonakala komphetho, ukwaphuka okanye ukukrwela umphezulu. Ukuphathwa okungaphezulu kwee-PCBS ezihlanganisiweyo kuhlala kuyingozi.

Yongeza i-Angle okanye irediyasi kwicandelo

Ngaba oku kuthintela ukubanakho ukusebenzisa indlela yokufumana amanqaku?

Hayi, kodwa usadinga imiphetho ethe tyaba ukuze ukhangele ibhodi. Ngokwesiqhelo, xa usebenzisa indlela yokubambisa, iiPCBS ziya kumisa idoksi kunye. Umsiki usika zombini ezantsi kunye nezantsi.

Ukuphazamisa ii-angles okanye i-radii, kuya kufuneka ushiye indawo phakathi kwePCBS. Umcwangcisi oqhelekileyo we-Router usebenzisa i-0.096 “cutter cutter efuna ubuncinci i-0.100” ukucoca phakathi kwamalungu. Kukho inkunkuma encinci phakathi kweendawo. Akucetyiswa ukuba kusetyenziswe i-0.100 “isithuba kunye notching iindlela phakathi kweebhodi, nokuba zinezixhobo, kunzima kakhulu ukuzaphula. Xa kufuneka indawo, kuyacetyiswa ukuba kusetyenziswe i-0.200 “okanye isithuba esikhulu seentsimbi.

Imithetho yoyilo lwePCB yabayili

Phendula umbuzo oqhelekileyo; Ewe unako ukulinganisa phantse nayiphi na ibhodi yesekethe eprintiweyo ngokuthe ngqo, kodwa kuya kufuneka usebenzise indibaniselwano yokufumana amanqaku kunye neencingo.

Ubushushu bomgangatho wokulaminetha ophakamileyo ongaphezulu kwe-150TG unezinto ezishinyeneyo kunye nolwakhiwo oluncinci. Sukusebenzisa iiparameter eziqhelekileyo ezisetyenziswe kwimilinganiselo esemgangathweni ye-130tg. Amaqhezu anzulu ayafuneka ukwaphula ngokulula ezi zinto ziphothiweyo zomeleleyo. Kwizinto ezinobushushu obuphezulu, sebenzisa i-0.015 “+/- 0.004” mesh.

Ukusuka kumda wentsimbi, umaleko wokhuseleko kufuneka ulungelelaniswe kubukhulu bebhodi yesekethe eprintiweyo. Xa ilingana okanye ingaphantsi kwe-0.062 “, umgama phakathi kwesinyithi kunye nomda wangempela weplate uya kuba ngu-0.015”. Le yinombolo efanelekileyo yesalathiso. Iibhodi ezityebileyo zingasetyenziselwa i-0.096 “okanye i-0.125” phezulu kunye ne-0.020 “okanye ngaphezulu ukuba indawo ivumela yonke imisebenzi ukusuka kumda wekhadi.

Kwiibhodi zesekethe eziprintiweyo ezingaphantsi kwe-0.040 “kubukhulu, soloko ucwangcisa ukusebenzisa iilugs zentsimbi ukunqanda naziphi na iingxaki.
