Iqondo lobushushu kunye nokufuma kwePCB yoGcino lweBhodi kunye nendlela yokuGcina?

ngophuhliso lobuchwepheshe be-elektroniki, iibhodi zeesekethe zisetyenziswa ngokubanzi kwiinkalo ezahlukeneyo, phantse zonke izixhobo zombane zineebhodi zesekethe.I-automotive ephezulu, i-aviation, i-electronics zonyango, ikhaya eliqhelekileyo eliqhelekileyo, i-electronics yonxibelelwano, izixhobo zekhaya, njl. njl. ubushushu bokugcina kunye nokufuma kunye nendlela yokugcina.

PCB ibhodi yokugcina iqondo lobushushu kunye nokufuma

Amanyathelo okuvelisa ibhodi PCB, kunye neemfuno kukusebenza igumbi ecocekileyo, ngoko ke ukwenziwa pcb kokusingqongileyo kunye neemfuno ubushushu kunye nokufuma zingqongqo ngokwentelekiso.Ubushushu kunye nomswakama akufanelekanga, kuya kukhokelela kwi-corrosion yebhodi ye-pcb, ukunciphisa ubomi besiphaluka kunye nokunciphisa ukusebenza kwebhodi.Ngoko ke ibhodi pcb kufuneka igcinwe kwindawo yokugcina ubushushu: 22-27 degrees, ukufuma: 50-60%.

PCB ibhodi indlela ukugcina kunye nokugcinwa ixesha

1. Ukuveliswa kwe-PCB kunye nokucubungula, kufuneka kube lixesha lokuqala lokusebenzisa ukupakishwa kwe-vacuum, kunye nebhegi yokupakisha i-vacuum kufuneka ibe ne-desiccant kunye nokupakishwa okuqinileyo, ayikwazi ukudibanisa namanzi kunye nomoya, ukuphepha ibhodi yesekethe ye-pcb yomphezulu wokutshiza i-tin kunye ne-pad bit yi-oxidation echaphazelayo. ukuwelda kunye nomgangatho wemveliso.

2. Iibhodi zePCB kufuneka zihlelwe kwaye zibhalwe, iibhokisi ezitywiniweyo kufuneka zihlulwe eludongeni, akufanele zibekwe kwindawo yokukhanya kwelanga, zigcinwe kwikhabhinethi yokugcina umoya kunye neyomileyo kunye nendawo yokugcina indawo efanelekileyo (ubushushu: 22-27 degrees, umswakama. : 50-60%).

3. Ixesha elide alisetyenziswanga ibhodi yesekethe pcb, eyona ilungileyo kwixesha ibhrashi umphezulu ezintathu anti-varnish, ukufuma-ubungqina, uthuli-ubungqina, anti-oxidation, ngoko pcb sesekethe yokugcina ibhodi ubomi kunokunyuswa ukuya kwiinyanga ezili-9.

4. Isiqwenga se-pcb esingapakishwanga sigqitywe kwiqondo elingaguqukiyo lobushushu kunye nokufuma kwindawo yogcino lweentsuku ezili-15, hayi ngaphezulu kweentsuku ezi-3 kwiqondo lobushushu begumbi.

5. I-pcb engapakishwanga kufuneka isetyenziswe ngaphakathi kweentsuku ezi-3, ingasetyenziswanga imfuneko yokuphinda isetyenziswe i-static bag vacuum itywinwe.

6. SMT patch kunye DIP emva ibhodi pcb ukuba zithuthwe kwaye ibekwe kunye isibiyeli anti-static.
