Zvinetso zvakajairika uye zvinopesana mukati FPC uye PCB maitiro ekugadzira

Nekushandurwa kwenzvimbo yekumonera kune isina-mhando mhando, pcb redunhu bhodhi inoda kutakura ultra-yakakwira kutonhora tembiricha, uye kudiwa kwekushisa kwekuvhunduka kusagadzikana kwekunze kwepasi solder kuramba rukoko kwakakwirira uye kwakakwirira. Iko kudiwa kweinogumira pamusoro kurapwa, peeling simba resa solder ramba ((inki, masking firimu) uye kunamatira ne base base mhangura yakakwira uye yakakwirira. Tinoda nani pre-kurapwa tekinoroji kuve nechokwadi. Nekuvandudza tekinoroji yedu, tinogona kunatsiridza goho rezvinhu uye kuwana purofiti kukura. Yakakwira mhando pre-kurapwa potion pasina mubvunzo inogona kutibatsira pamutengo wakaderera.

Ichi chinyorwa chinonyanya kuunza mibvunzo uye maCountermeasure anowanzo sangana nawo mukugadzirwa kwePCB uye FPB yakapfava redunhu bhodhi: chekutanga, chikamu chemutsara chinopa kuderera kwemhepo uye kuratidzika kwe concave kana kuchinjisa mutsetse mushure mekuoma kwefirimu kana kurapwa kwemafirimu manyoro, zvichikonzera kushayikwa kwetambo upamhi kana mutsetse usina kuenzana. Icho chikonzero hachisi chimwe chinhu kunze kwekusarudzika kusarongeka kweakaoma uye akanyorova mafirimu data, zvisirizvo ekuratidzira parameter uye isina kunaka mashandiro ekuratidzira muchina. Kubudirira, etching chikamu kamwene kugadzirisa, kusagadzikana mamiriro ezvinhu ane hukama parameter, kukosheswa kwakashata uye chiyero chemushonga wemvura, kumhanyisa kutapudza kumhanya uye zvimwe zvakateedzana zvinogona kukonzera mibvunzo. Nekudaro, isu tinowanzoona kuti hapana chakajairika nekutarisa zviyero zviri pamusoro pamwe nemashandisirwo emidziyo inoenderana, asi kuchine mibvunzo yakadai seye pamusoro pekuora uye concave corrosion yebhodi redunhu kana uchigadzira bhodhi. Chii chiri chikonzero shure kwezvose?

2, Kana tichiita pcb pateni electroplating uye pamusoro kurapwa kwePCB uye FPC zviteshi, senge kuisirwa goridhe, yemagetsi goridhe, magetsi tini, kemikari gaba uye kumwe kurapwa kwehunyanzvi, isu tinowanzoona kuti mabhodhi akagadzirwa anoratidza kuoneka kwekupinda kwakapinza kumucheto yefirimu yakaoma uye yakanyorova kana solder inodzivisa dura, kana mazhinji emabhodhi kana mamwe emabhodhi emuno, Zvisinei nemamiriro ezvinhu, ichaunza kukanzura kusingakoshi kana kuremara, dambudziko risingakodzeri rekugadziriswa, uye kunyangwe kukanzuru , izvo zvinoshungurudza! Icho chikonzero ndechekuti isu tinowanzo funga nezve iyo yakaoma uye yakanyorova parameter mafirimu, uye iro basa re data riri kusahadzika; Pane mibvunzo nezve solder kuramba, senge inki kune rakaomarara bhodhi, masking firimu kune yakapfava bhodhi, kana mibvunzo mukudhinda, kudzvanya, kuporesa uye zvimwe zvikamu. Chokwadi, imwe neimwe yenzvimbo idzi inogona kukonzera kusahadzika uku. Ipapo isu tavhiringidzikawo kuti hapana kupokana kana kusahadzika muchikamu chepamusoro chechitanho, asi zvicharamba zvichiratidza kuoneka kwekupinda kwakaputira. Mushure mezvose, chii chikonzero chekusaziva?

3, pcb mabhodhi achaedzwa netini isati yatumirwa. Ehe, vatengi vanoshandisa tini yakasungwa zvinhu. Pane kusahadzika kuti inki inogona kushenurwa zvakanyanya kana kuti simba rekufukura remasking firimu replate nyoro kushomeka kana kusaenzana, Vatengi, kunyanya avo vanoita zvakanaka SMT kumisikidza, havagone kutakura mibvunzo yakadaro. Kamwe iyo solder inodzivisa rukoko ichipa kuoneka kwechiedza peeling panguva yekumonera, zvinoita kuti zvikone kunyatso nyatso kugadzira iyo yekutanga, zvichikonzera kurasikirwa kwezvakawanda zvezvinhu uye kunonoka kwebasa nevatengi. Iyo redunhu bhodhi fekitori inosangana nekurasikirwa kwakakura senge kubviswa, zvinhu zvekuwedzera, uye kunyangwe kurasikirwa kwevatengi. Saka zvinhu zvipi zvatinowanzotanga nazvo kana tasangana nemibvunzo yakadai? Isu tinowanzo tarisa kana iri solder kuramba (inki, masking film) data; Pane here kusahadzika panguva yesiriki yekudhinda screen, lamination uye kurapa; Pane paine kusahadzika here pamusoro pesarudzo yeelectroplating? mira… Naizvozvo, isu tinowanzo kuraira mainjiniya kuti vazive chikonzero uye nekuvandudza kubva kuzvikamu izvi. Isuwo tinoshamisika kana iri mamiriro ekunze? Yakanyorova nguva pfupi yadarika, uye bhodhi rinotora mwando? (PCB substrate uye chipingamupinyi zviri nyore kutora mwando) kuburikidza nebasa rakaomarara, vanogona kukohwa zvimwe zvinokanganisa. Zviri kusahadzika kuti ivo vanozorapwa kunze kwechinguva chiripo.
