Amasu Wokuhlanganisa we-PCB enamacala amabili

Izici zebhodi lesifunda elinamahlangothi amabili

Single-emaceleni wesifunda ibhodi futhi kabili emaceleni wesifunda ibhodi umehluko inani izingqimba zethusi uhlukile.Double emaceleni wesifunda ibhodi ibhodi nhlangothi zombili zethusi, kungaba ngokusebenzisa imbobo ukudlala indima yokuxhuma.Single-emaceleni kuphela ungqimba zethusi, kungenza kuphela umugqa olula, imbobo eyenziwe ingasetshenziswa kuphela plug-in ayikwazi conduction.

Izidingo zobuchwepheshe zebhodi lesifunda elinezinhlangothi ezimbili ukuminyana kwezintambo kuba kukhudlwana, ububanzi bembobo encane, ububanzi bembobo obuyinsimbi bubuye bube buncane.Ukuhlanganiswa kwesendlalelo nesendlalelo kuncike emgodini we-metallization, ikhwalithi ihlobene ngokuqondile nokuthembeka kwebhodi lesifunda eliphrintiwe.

Ngokuncishiswa kwembobo, indawo yokuqala eya endaweni enkulu yokuvula ayizange ithinte imfucumfucu, njengokugaya imfucumfucu, umlotha wentaba-mlilo, uma ususele emgodini omncane ongaphakathi, uzokwenza i-chemical precipitation ibe yithusi, i-copper plating ilahlekelwe umphumela, umgodi. ngaphandle kwethusi, abe imbobo metallization of the killer obulalayo.

Indlela yokushisela ibhodi lesifunda elinamahlangothi amabili

Ibhodi lesekhethi elinamacala amabili ukuze kuqinisekiswe ukuthi isekethe enamacala amabili inomphumela othembekile wokuqhuba, sincoma ukuthi uqale usebenzise izintambo kanye nokunye ukushisela imbobo yokuxhuma kuphaneli ezinhlangothi zombili (okungukuthi, inqubo yokwenza insimbi ngokusebenzisa ingxenye yembobo), futhi usike ithiphu yomugqa wokuxhuma ingxenye ephumela, ukuze ungagwazi isandla somqhubi, okuwumsebenzi wokulungiselela ukuxhuma kwebhodi.

Izinto ezibalulekile zokushisela ibhodi lesifunda elinamahlangothi amabili

1. Kunezidingo zokubunjwa kwedivayisi kufanele kuhambisane nezidingo zenqubo yemidwebo yenqubo;okungukuthi, ukubumba okokuqala ngemuva kwe-plug-in.

2. ngemva kokubumba uhlangothi lwemodeli ye-diode kufanele lubheke phezulu, akufanele kube nokungahambisani nobude bezikhonkwane ezimbili.

3. idivayisi enezimfuneko ze-polarity lapho ifakwe ukuze inake ukuhlukana kwayo akufanele ifakwe emuva, izingxenye zebhulokhi edidiyelwe yomqulu, ngemva kokufaka, noma ngabe idivayisi emile noma elele, akumele kube khona ukutsheka okusobala.

4. Amandla ensimbi e-soldering angu-25 kuya ku-40W, ukushisa kwekhanda lensimbi e-solder kufanele kulawulwe cishe ku-242 ℃, izinga lokushisa liyikhanda eliphakeme kakhulu kalula "lifile", izinga lokushisa liphansi alikwazi ukuncibilikisa i-solder, ukulawula isikhathi sokuthengisa ngo-3 kuya ku-4. imizuzwana.

5.Geza kabusha ihhavini or umshini we-wave solderingWelding esisemthethweni ngokuvamile ngokuhambisana idivayisi kusukela iDemo kuya phezulu, kusukela ngaphakathi kuya ngaphandle isimiso Welding ukusebenza, Welding isikhathi master, eside kakhulu ngeke ashise idivayisi, uyophinde ashise imigqa yethusi abagqoke izingubo zethusi. ibhodi.

6. Ngenxa yokuthi i-welding kabili emaceleni, ngakho-ke kufanele futhi wenze inqubo yokubeka ifreyimu yebhodi lesifunda nokunye, inhloso ayikona ukucindezela i-oblique ngaphansi kwedivayisi.

7. ngemuva kokuphothulwa kwe-soldering yebhodi lesifunda kufanele kube isheke elibanzi ngenombolo yohlobo, hlola indawo lapho kukhona ukuvuza kokufakwa nokuvuza kwe-welding, ukuze uqinisekise ibhodi lesifunda amadivayisi angasebenzi njenge-pin trimming, ngemuva ageleza kunqubo elandelayo.

I-8, ekusebenzeni okuqondile, kufanele futhi ilandele ngokuqinile amazinga enqubo efanele ukuze isebenze ukuze kuqinisekiswe ikhwalithi ye-welding yomkhiqizo.

Ngokuthuthuka okusheshayo kobuchwepheshe obuphezulu, kanye nobudlelwano obuseduze bomphakathi nemikhiqizo ye-elekthronikhi ekuvuselelweni okuqhubekayo, umphakathi nawo udinga ukusebenza okuphezulu, usayizi omncane, imikhiqizo ye-elekthronikhi enemisebenzi eminingi, ebeka phambili izidingo ezintsha zebhodi lesifunda.

Ngakho-ke ibhodi lesifunda elinamaceleni amabili liyazalwa, ngenxa yokusetshenziswa kabanzi kwebhodi lesifunda elinamaceleni amabili, okwenza ukuthi ukukhiqizwa kwebhodi lesifunda eliphrintiwe futhi kube nokukhanya, okuncane, okufushane, ukuthuthukiswa okuncane.
