I-PCBA Processing Pads azikho kuHlahlelo lweSizathu seTin

Ukusetyenzwa kwe-PCBA kwaziwa ngokuba yi-chip processing, ngaphezulu umaleko ophezulu ubizwa ngokuba yi-SMT processing, ukusetyenzwa kwe-SMT, kuquka i-SMD, iplagi ye-DIP, uvavanyo lwe-post-solder kunye nezinye iinkqubo, isihloko seepads azikho kwi-tin ikakhulu kwi-toti. SMD processing link, intlama ezele amacandelo ahlukeneyo ebhodi savela kwibhodi yokukhanya PCB, pcb ukukhanya ibhodi inamaphedi amaninzi (ukubekwa amacandelo ahlukeneyo), ngokusebenzisa-umngxuma (plug-in), iipads azikho itoti. okwenzekayo ngoku Imeko ingaphantsi, kodwa kwi-SMT ngaphakathi kukho udidi lweengxaki zomgangatho.
Iingxaki zenkqubo yomgangatho, zibopheleleke ukuba zibe zizizathu ezininzi, kwinkqubo yokuveliswa kwemveliso, kufuneka zisekelwe kumava afanelekileyo ukuqinisekisa, enye nenye ukusombulula, ukufumana umthombo wengxaki kunye nokusombulula.

I. Ukugcinwa okungafanelekanga kwePCB

Ngokubanzi, itoti yokutshiza ngeveki iya kubonakala i-oxidation, unyango lomphezulu we-OSP lunokugcinwa iinyanga ezi-3, ipleyiti yegolide etshoneyo inokugcinwa ixesha elide (okwangoku iinkqubo zokuvelisa ze-PCB zininzi)

II.Ukusebenza ngokungafanelekanga

Indlela ye-welding engalunganga, amandla aneleyo okufudumeza, akwanele ubushushu, ixesha lokubuyela kwakhona kunye nezinye iingxaki.

III.Iingxaki zoyilo lwePCB

I-solder pad kunye nendlela yokudibanisa ulusu lobhedu iya kukhokelela ekufudumezeni kweepadi ngokwaneleyo.

IV.Ingxaki yokuguquguquka

Umsebenzi we-Flux awonelanga, iipads zePCB kunye ne-electronic components soldering bit ayisusi izinto ze-oxidation, i-solder joints bit flux ayikwanelanga, okubangela ukumanzisa okungahambi kakuhle, ukuguquguquka kwi-tin powder akushukunyiswa ngokupheleleyo, ukusilela ukudibanisa ngokupheleleyo kwi-flux. (i-solder paste ibuyele kwixesha lobushushu lifutshane)

V. PCB ibhodi ngokwayo ingxaki.

Ibhodi ye-PCB kumzi-mveliso ngaphambi kokuba i-oxidation ye-pad inganyangwa
 
VI.Hlaziya i-oveniiingxaki

Ixesha lokufudumala lifutshane kakhulu, iqondo lobushushu liphantsi, i-tin ayinyibiliki, okanye ixesha lokufudumala lide kakhulu, ubushushu buphezulu kakhulu, okubangela ukusilela komsebenzi we-flux.

Ukususela kwezi zizathu zingasentla, ukusetyenzwa kwe-PCBA luhlobo lomsebenzi alukwazi ukuba li-sloppy, inyathelo ngalinye kufuneka libe ngqongqo, kungenjalo kukho inani elikhulu leengxaki ezisemgangathweni kuvavanyo lwe-welding kamva, ngoko kuya kubangela inani elikhulu kakhulu labantu, ilahleko zemali nezinto, ngoko PCBA processing phambi kovavanyo lokuqala kunye neqhekeza lokuqala SMD kuyimfuneko.
