Ishicilelwe ibhodi yesekethe have many uses in technology. Nangona kunjalo, kubiza imali ngakumbi ukwenza uvavanyo lwembono ngaphambi kokuya kwimveliso yePCB. PCB prototype boards allow ideas to be approved cheaply before a full print version is produced.

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

Indlela yokusebenzisa ibhodi prototype PCB

Before you can learn more about how to use A PCB prototype board, you must understand the different types of prototype boards available.

Perforated plate

Performance boards are one of the available types of prototype boards. 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.

The strip plate

Njengazo zonke ii-PCBS zomzekelo oqhelekileyo, iplagboard ikwanokuseta imingxunya eyahlukileyo. Instead of a single conductor pad for each perforation, copper strips run parallel to the length of the circuit board to connect the holes, hence the name. Ezi ziqwengana zithatha indawo yeengcingo onokuzikhulula.

Both types of PCB prototypes work well on the planning board. 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

Even if you know how to use a PCB prototype board, you don’t want to jump right into 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. If stripper boards are used, it is also helpful to indicate where you plan to interrupt the stripper.

Digital programs allow you to edit ideas faster, but hand-drawn content can help you target projects in different ways. 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. Repeat on the other side, then place the prototype board on the edge of a flat surface such as a table. Ungayibamba ngokucocekileyo ibhodi ngokwamanqaku akho.

Experts suggest that a cleaner fracture can be obtained by marking along the position of the hole in the board, because there is no such stable prototype board that can break and break easily.

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

Bread board to strip board

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.
