heino goridhe nemhangura mumabhodhi edunhu emafoni nemakomputa. Naizvozvo, mutengo wekudzokorodza weakashandiswa edunhu mabhodhi unogona kusvika kudarika 30 yuan pakirogiramu. Inodhura zvakanyanya pane kutengesa marara mapepa, mabhodhoro egirazi, uye simbi yakarakwa.

Kubva kunze, chikamu chekunze chebhodhi redunhu chinonyanya kuve nemavara matatu: goridhe, sirivha, uye chiedza chitsvuku. Ndarama ndiyo inodhura zvakanyanya, sirivha ndiyo yakachipa, uye tsvuku tsvuku ndiyo yakachipa.

Inogona kuonekwa kubva muvara kana mugadziri we hardware akacheka makona. Mukuwedzera, dunhu remukati rebhokisi redunhu rinonyanya kuchena mhangura, iyo iri nyore oxidized kana yakaratidzwa kumhepo. Iyo yekunze yekunze inofanira kunge iine yataurwa pamusoro pekudzivirira. Vamwe vanhu vanoti goridhe yero imhangura, izvo zvisiri izvo.

Ndarama

Ndarama inodhura zvakanyanya igoridhe chairo. Kunyangwe kuchingori mutete mutete, zvakare inoverengera ingangoita 10% yemutengo wedunhu redunhu. Dzimwe nzvimbo dziri pamhenderekedzo yeGuangdong neFujian dzinonyanya kutenga marara ematunhu ematunhu uye kupepeta goridhe. Mapurofiti akawanda.

Pane zvikonzero zviviri nei goridhe richishandiswa, chimwe ndechekugonesa welding, uye chimwe chekudzivirira ngura.

Chigunwe chegoridhe chememory module makore masere apfuura chichiri kupenya, kana ukachichinja kuita mhangura, aruminiyamu, kana simbi, ichava ngura uye isina basa.

Iyo goridhe-yakanamirwa layer inoshandiswa zvakanyanya muchikamu mapedhi, zvigunwe zvegoridhe, uye shrapnel yekubatanidza yedare redunhu.
Kana iwe ukaona kuti mamwe ematunhu mapuranga ese esirivha, iwe unofanirwa kunge uchicheka makona. Izwi reindasitiri rinonzi "costdown".

Nharembozha mamaboards anonyanya kuve mabhodhi-akaputirwa negoridhe, nepo makomputa mamabhodhi, odhiyo uye madiki edhijitari edunhu mabhodhi kazhinji haasi mabhodhi akaputirwa negoridhe.

Sirivha
Ko, aureate imwe yegoridhe uye sirivha imwe sirivha here?
Kwete kwete, irata.

Sirivha bhodhi rinonzi spray tin board. Kupfapfaidza dhiri rematani pachikamu chekunze chedunhu remhangura kunogona kubatsirawo kusona. Asi haigone kupa kuvimbika kwekusangana kwenguva refu segoridhe.

Iyo yekupfapfaidza tin ndiro haina mhedzisiro pane izvo zvakatengeswa, asi kuvimbika hakuna kukwana kune mapedhi ayo akaiswa pachena kumhepo kwenguva yakareba, senge pasi pedhi uye chitubu pin sockets. Kushandiswa kwenguva refu kunowanzoita oxidation uye corrosion, zvichikonzera kusabatana kwakashata.

Mabhodhi edunhu ezvigadzirwa zvidiki zvedhijitari, pasina kusarudzika, mabhodhi espray tin. Pane chikonzero chimwe chete: zvakachipa.

Zvigadzirwa zvidiki zvedhijitari zvinoda kushandisa ndiro yekupfapfaidza.

Chitsvuku
OSP, organic soldering firimu. Nekuti iri organic, kwete simbi, yakachipa pane kumwaya marata.

Izvo chete basa reiyi organic firimu kuve nechokwadi chekuti mukati mendarira foil haizove oxidized isati yatungidzirwa. Iyi firimu yefirimu inoputika kana ichinge yapiswa panguva yewelding. Solder inogona weld waya yemhangura nezvinoumba pamwechete.

Asi haidziviriri kune ngura. Kana OSP redunhu bhodhi rakaratidzwa kumhepo kwemazuva gumi, harizokwanisi kupinza zvinhu.

Mazhinji makomputa mamabhodhi anoshandisa OSP tekinoroji. Nekuti nzvimbo yedare redunhu yakakura kwazvo, haigone kushandiswa kugadzira goridhe.
