Ishicilelwe ibhodi yesekethe zinokusetyenziswa okuninzi kwitekhnoloji. Nangona kunjalo, kubiza imali ngakumbi ukwenza uvavanyo lwembono ngaphambi kokuya kwimveliso yePCB. Iibhodi zemizekelo ye-PCB zivumela izimvo ukuba zamkelwe ngexabiso eliphantsi ngaphambi kokuba kuveliswe ingxelo epheleleyo.

Kweli nqaku, siza kugubungela iintlobo ezahlukeneyo ezikhoyo kunye nendlela yokusebenzisa iibhodi zePCB zokucwangcisa uyilo lokugqibela lwebhodi yesekethe.

Indlela yokusebenzisa ibhodi prototype PCB

Phambi kokuba ufunde okungakumbi malunga nendlela yokusebenzisa i-PCB yebhodi yeprototype, kufuneka uqonde iintlobo ezahlukeneyo zeebhodi zomzekelo ezikhoyo.

Ipleyiti tyaba

Iibhodi zokusebenza yenye yeentlobo ezikhoyo zeebhodi zeeprototype. Olu luhlu lukwaziwa ngokuba luyilo “lomngxuma ngamnye”, apho umngxunya ngamnye unephedi yomqhubi eyenziwe ngobhedu. Usebenzisa olu seto, ungavavanya unxibelelwano lwe-solder phakathi kweepads ezizodwa. Ukongeza, unokucoca ucingo phakathi kweepads kwiipleyiti ezigqabhukileyo.

Isipleyiti

Njengazo zonke ii-PCBS zomzekelo oqhelekileyo, iplagboard ikwanokuseta imingxunya eyahlukileyo. Endaweni yephedi yomqhubi enye yokugcotywa nganye, imitya yobhedu ihambelana ngokuhambelana nobude bebhodi yesekethe ukudibanisa imingxunya, kungoko igama. Ezi ziqwengana zithatha indawo yeengcingo onokuzikhulula.

Zombini ezi ntlobo zeeprototypes ze-PCB zisebenza kakuhle kwibhodi yocwangciso. Ngenxa yokuba iingcingo zobhedu sele zidityanisiwe, iiplagi zebhodi nazo zilungile ekucwangciseni iisekethe ezilula. Nokuba yeyiphi na indlela, uya kusebenzisa i-prototype plate welding kunye ne-prototype plate wire ukuvavanya iibhodi ezinokubakho.

Ngoku ukulungele ukufunda okungakumbi malunga nendlela yokusebenzisa uyilo lwebhodi yokubonisa ngokweenkcukacha.

cwangciso

Nokuba uyayazi ukuba uyisebenzisa njani ibhodi yohlobo lwePCB, awufuni ukutsiba ungene prototyping. Nangona iibhodi zeprototype zitshiphu kakhulu kuneebhodi zesekethe eziprintiweyo, zisenoqwalaselo oluzinzileyo. Ngaphambi kokuba uqale ukubeka izinto, kuya kufuneka uchithe ixesha elithile kwisigaba sokucwangcisela ukufumana ezona ziphumo zihle.

Indlela ethe ngqo yokuqalisa kukusebenzisa isicelo sokucwangciswa kwebhodi yesekethe kwikhompyuter. Isoftware enjalo ikunika ithuba lokujonga isekethe ngaphambi kokubeka phantsi naziphi na izinto. Qaphela ukuba ezinye iinkqubo zisebenza kakuhle ngePerf kunye neStripboard, ngelixa ezinye zisebenza ngohlobo olunye kuphela, ke cwangcisa ukuthenga iibhodi zemodeli ngokufanelekileyo.

Ukuba ufuna ukusebenzisa isisombululo esincinci sedijithali, unokusebenzisa iphepha lesikwere kuyilo lwebhodi yokubonisa. Uluvo kukuba yonke indawo apho imigca iwela khona ngumngxuma ebhodini. Izixhobo kunye neengcingo zinokutsalwa. Ukuba kusetyenziswa iibhodi ezihlwitha, kuyanceda ukubonisa apho uceba ukuphazamisa khona.

Iinkqubo zedijithali zikuvumela ukuba uhlele izimvo ngokukhawuleza, kodwa umxholo owenziwe ngesandla unokukunceda ujolise kwiiprojekthi ngeendlela ezahlukeneyo. Nokuba yeyiphi na indlela, musa ukutsiba isigaba sokucwangcisa, njengoko ungonga ixesha kunye nomzamo xa usakha iProtoboard.

Ukusika ibhodi yokubonisa

Nge-Protoboard, ngekhe ulidinge lonke iphepha. Kuba iibhodi zinokwahluka ngokobukhulu, unokufuna ukusika enye. Lumka, nangona kunjalo, njengoko le nkqubo inokuba nzima.

Inxalenye yesizathu kungenxa yemathiriyeli ekwibhodi yomzekelo. Uyilo luhlala lucoca iphepha nge-resin ephikisana nobushushu be-soldering, eluncedo kakhulu xa ungena kweli nqanaba. Ukungancedi kukuba le resin inokuphula ngokulula ipleyiti yoqobo, ke kungcono ukuba uqaphele.

Enye yeendlela ezifanelekileyo nezichanekileyo zokusika ibhodi yomzekelo kukusebenzisa irula kunye nemela ebukhali. Ungasebenzisa umphetho njengesikhokelo sokusika imigca apho ufuna ukusika khona ibhodi. Phinda kwelinye icala, emva koko ubeke ibhodi yomzekelo kumda wendawo ethe tyaba njengetafile. Ungayibamba ngokucocekileyo ibhodi ngokwamanqaku akho.

Iingcali zicebisa ukuba ukwaphuka okucocekileyo kunokufumaneka ngokumakisha kwindawo yomngxunya ebhodini, kuba akukho bhodi yomzekelo izinzileyo inokuqhekeka kwaye yaphuke ngokulula.

Iisarha zebhendi kunye nezinye izixhobo zebhendi zinokusetyenziswa, kodwa ezi zixhobo zinokwenzeka kakhulu ukuba zonakalise ibhodi yeprototype kwinkqubo.

Ibhodi yesonka yokuhluba ibhodi

Ukuba wenze nawuphi na umsebenzi kwiprototype yePCB, usenokudibana nebhodi yesonka. Ezi bhodi zemizekelo zilungile ekuphuhliseni uyilo kuba ungahambisa kwaye utshintshe izinto ukwakha izicwangciso. Iibhodi zezonka zinokusetyenziswa kwakhona.

Kule meko, ubeko lwecandelo linokuhanjiswa kwibhodi yomcu ukuze kuvavanywe ngakumbi. Ukongeza, iribhoni kunye neebhodi zemodeli ezigqityiweyo azithintelekanga kuba unokwenza unxibelelwano oluntsonkothileyo. Ukuba ucwangcisa ukusuka kwibhodi yesonka uye kwibhodi yokuhlutha, unokunceda ekuthengeni ibhodi yokuqhekeza ehambelana nomgaqo okanye ukutshabalalisa umkhondo webhodi yokuqhekeza.

Ukuba ufuna iisekethe zethutyana zibe nolungelelwaniso olomeleleyo nolusisigxina, ukuhambisa izinto ukusuka kwisonka ukuya kwibhodi yokuhlutha yenye yeendlela ezilula.

Yahlula amanqaku ebhodi

Njengoko bekutshiwo ngaphambili, ibhodi yebhodi ye-PCBS ineemicu zobhedu emazantsi ezisebenza njengonxibelelwano. Nangona kunjalo, awuyi kudinga ukuqhagamshela onke amacandelo ngalo lonke ixesha, ke kuyakufuneka ukuba wophule le mida.

Ngethamsanqa, yonke into oyifunayo kukuqhuba. Into ekufuneka uyenzile kukuthatha i-4mm drill bit kwaye ucofe i-nib emngxunyeni ofuna ukuyikhupha. Ngokujija nje kancinci noxinzelelo, ubhedu lunokunqunyulwa ukwenza umqobo wokuthintela. Xa ufunda indlela yokusebenzisa ibhodi ye-PCB yamacala amabini, qaphela ukuba ifoyile yobhedu ingapha nangapha.

Ukuba ufuna into ehambele phambili kunesilinganiselo esisezantsi, ungasebenzisa izixhobo ezithile ukunqamla olu nxibelelwano, kodwa indlela ye-DIY isebenza ngokunjalo.

siphelo

Ukwazi ixesha kunye nendlela yokusebenzisa iibhodi zemizekelo sisakhono esibalulekileyo kuye nabani na ofuna ukuyila nokuvavanya iibhodi zesekethe ngaphandle kwendleko zokuziprinta. Ngeebhodi zeeprototype, unokwenza amanyathelo amakhulu ekugqibezeleni imveliso yakho.
