Indlela yokufaka amagoli i-V isetshenziswe iminyaka eminingi ekukhiqizeni i- ibhodi yesifunda ephrintiwe (I-PCB). Ngobuchwepheshe bokukhiqiza be-PCB obuguquka ngokushesha, kubalulekile ukuthi wazi izinkombandlela zakamuva zokufaka amagoli ze-PCB okufanele uzilandele nokuthi zingahluka kanjani kulokho owake wakusebenzisa ngaphambilini.

Inqubo yokufaka amagoli ifaka izindwani ezimbili ezijikeleza ngokusondelana zikhombe iphuzu lapho iphuzu lihamba phakathi kwamakhasi. Le nqubo icishe ifane nokusika i-pizza ku-pancake, ukusika i-pizza ibe izingcezu ezincanyana bese ngokushesha uhambisa umkhiqizo esinyathelweni esilandelayo, esingathuthukisa ukukhiqizwa okuphelele. Ngakho-ke kufanele usebenzise amagoli nini ku-PCB yakho? Yiziphi izingqinamba ezingaba khona zale nqubo?

Ibhodi lesifunda eliphrintiwe

Noma ngabe i-PCB yakho iyisikwele noma ingunxande, zonke izinhlangothi zinemigqa eqondile futhi zingasikwa kumshini we-V-notch. Umbuzo okufanele ubuzwe ukuthi, ingabe ukulungele ukugreda, noma ngabe kukhona ezinye izindawo ezidinga ukulungiswa? Ukushaya noma ukungashayi amaphuzu? Nazi izizathu ezimbalwa zokwenqaba ukuphendula.

Amaphuzu amancane we-PCBS

Amabhodi wesekethe aphrintiwe mancane kunama-intshi ayi-0.040 kunzima ukuwabeka ngezizathu ezithile. Kudingeka ubuncane obungu-0.012 “ukuvikela ikhoyili emise okwe-V, njengoba insimbi (ikhoyili) yebhetshi yesobunxele isethwe ngasikhathi sinye notch 0.010” – ukujula kuka-0.012 “ezinhlangothini zombili kuzokwenza i-0.020” +/- 0.004 “ inetha lincane kuno-0.040 ”.

Amabhodi wesifunda aphrintiwe we-Thinner anokuphambuka okuthile kuphela kulokho okubhaliwe. I-PCBS eguquguqukayo isebenzisa indlela yekhefu engafakwanga ingashiya imiphetho emibi futhi ilenga imicu. Ukulawula inqubo yokufaka amagoli ngezinto ezisetshenzisiwe nokuvumela ukuphazamiseka okukhulu kunzima kakhulu. I-blade ibaluleke kakhulu ekubekeni kokubekezelelana kokujula kwenothi kusuka phezulu kuye phansi, futhi kukhona uhla oluqinile lokunemba ukuqinisekisa ukuthi okubanzi akuphuli ngesikhathi somhlangano. Lapho ukujula kwenothi kungalingani phakathi kwesobunxele nesokudla, ingxenye kuzoba nzima kakhulu ukuyiphula, kushiye imicu kanye nemiphetho yokuqhekeka okungenzeka.

I-PCB kumalungu afanayo ifakiwe

Lapho kusetshenziswa ukubhala okuningi, amandla wepaneli angahle abe buthakathaka, okuholele ekuphatheni okuntekenteke, kumalungu afanayo awonakele kanye / noma ezinkingeni zomhlangano.

Izingxenye ezinezilinganiso ezincane

Uma incane iyisentimitha lesikwele sebhodi, kuba nzima kakhulu ukunqamula. Lapho usayizi we-PCB umncane, amabhodi akhudlwana kuno-0.062 “kunzima kakhulu ukuwahlukanisa. Ngaphansi kweyintshi eli-1 kunhlangothi zombili kungadinga amathuluzi angeziwe ukwehlukanisa izingxenye.

Amaphuzu i-PCB ende kakhulu

Amabhodi wesifunda aphrintiwe ano-X noma Y omude (amasentimitha ayi-12 noma ngaphezulu) angahle abe buthakathaka futhi aphuke kalula uma eklwebhwe ngokujulile. Ukungeza izinto ezisindayo kumalungu afanayo asevele ebuthakathaka kungadala ukuthi amaphaneli aphuke ngesikhathi sokuphathwa, ukuhlangana, noma ukuthuthwa. Ukuqalisa izikolo zokugxuma noma umzila wethebula kungaba yindlela engcono.

Ipuleti lokushaya amagoli

Uma ubeka i-PCBS enkulu kunama-intshi ayi-0.096 ubukhulu, sebenzisa uhlelo olufanayo, ngamakhasi amabili asika ajule ebusweni bendawo, kushiye inetha elingu-0.020 amayintshi +/- 0.004 amayintshi. Ngaphezulu kwalokhu ubukhulu, kunzima ukuphula, ngoba ukugoba akwanele. Izindwangu ezijiyile zingasebenzisa le ndlela kumabhodi amakhulu, kepha kwesinye isikhathi kungaholela ezinkingeni zethusi ezikhaleni ezinqenqemeni.

Ithuluzi lokufaka amagoli

Kunamathuluzi atholakalayo okusiza ekunqandeni ama-PCBS. Kodwa-ke, kufanele isetshenziswe kahle futhi ibhekwe ngokunemba ukuvimbela ukulimala komphetho, ukwephuka noma ukuklwebheka komhlaba. Ukuphathwa okwengeziwe kwama-PCBS ahlanganiswe ngokugcwele kuhlale kuyingozi.

Faka i-engela noma irediyasi engxenyeni

Ingabe lokhu kuvimbela ikhono lokusebenzisa indlela yokushaya amagoli?

Cha, kepha usadinga imiphetho eyisicaba ukuklwebha ibhodi. Imvamisa, lapho usebenzisa indlela yokuchofoza, i-PCBS izothekelana. Umsiki usika kokubili phezulu nangaphansi.

Ukudunga ngama-engeli noma i-radii, kufanele ushiye isikhala phakathi kwe-PCBS. I-Router planer ejwayelekile isebenzisa i-0.096 “cutter cutter edinga okungenani u-0.100” ukuze igaye ngokuhlanzekile phakathi kwezingxenye. Kukhona nodoti omncane phakathi kwezingxenye. Akunconyelwe ukusebenzisa izindlela eziyi-0.100 “zokuhlukanisa nezikhala phakathi kwamabhodi, ngisho nangamathuluzi, kunzima kakhulu ukuwaphula. Lapho isikhala sidingeka, kunconywa ukusebenzisa u-0.200 “noma isikhala esikhulu samantongomane.

Imithetho ye-PCB design yabaqambi

Phendula umbuzo ojwayelekile; Yebo, ungaklelisa cishe noma yiliphi ibhodi lesifunda eliphrintiwe onqenqemeni oluqondile, kepha kungadingeka ukuthi usebenzise inhlanganisela yokushaya amagoli nokuhlanganisa izintambo.

Izinga lokushisa eliphakeme laminated ngezinto eziphakeme kune-150TG linempahla eminyene ne-microstructure. Ungayisebenzisi imingcele yezingxenyana esezingeni esetshenziswe kumazinga wezinto ezingama-130tg. Izingxenyana ezijulile ziyadingeka ukuze wephule kalula le nto eboshwe kakhulu. Ngezinto zokushisa eziphakeme, sebenzisa i-mesh engu-0.015 “+/- 0.004”.

Kusuka kunsimbi onqenqemeni, ungqimba lokuvikela kufanele luhlelwe ngokwezifiso zebhodi lesifunda eliphrintiwe. Uma ilingana noma ingaphansi kuka-0.062 “, ibanga phakathi kwensimbi nonqenqemeni lwangempela lwensimbi kufanele okungenani libe ngu-0.015“. Le yinombolo enhle yesethenjwa. Amabhodi amakhulu angasetshenziswa u-0.096 “noma u-0.125” phezulu no-0.020 “noma ngaphezulu uma isikhala sivumela yonke imisebenzi kusuka emaphethelweni ekhadi.

Kumabhodi wesekethe aphrintiwe angaphansi kuka-0.040 “ngobukhulu, hlala uhlela ukusebenzisa kuphela izingalo ukwenza izintambo ukugwema noma yiziphi izinkinga.
