Inkqubo ephambili yeNdibano yePCB

I-PCBA yinkqubo yokunyuswa kwamalungu e-elektroniki kwi-PCB.

Siphatha zonke izigaba kwindawo enye kuwe.

1. Ushicilelo lwe-Solder Paste

Inyathelo lokuqala kwindibano yePCB kushicilelo lwencama ye-solder kwiindawo zephedi zebhodi yePCB. I-solder paste iqukethe i-tin powder kunye ne-flux kwaye isetyenziselwa ukudibanisa amacandelo kwiipads kumanyathelo alandelayo.

2. ITekhnoloji eFakelwe phezu komhlaba (SMT)

I-Surface Mounted Technology(amacandelo e-SMT) abekwe kwi-solder paste kusetyenziswa i-bonder. I-bonder inokukhawuleza kwaye ibeke ngokuchanekileyo icandelo kwindawo ethile.

3. I-Reflow Soldering

I-PCB enamacandelo adityanisiweyo idlulela kwi-oven yokubuyisela, apho i-solder paste inyibilika kwiqondo lokushisa eliphezulu kunye namacandelo athengiswa ngokuqinile kwi-PCB. I-Reflow soldering linyathelo eliphambili kwindibano ye-SMT.

4. UHlolo oluBonakalayo kunye noHlolo oluSebenzayo lwaMacho (AOI)

Emva kokuthengiswa kwakhona, ii-PCBs zijongwa ngokubonakalayo okanye zihlolwe ngokuzenzekelayo kusetyenziswa izixhobo ze-AOI ukuqinisekisa ukuba zonke iinxalenye zithengiswa ngokuchanekileyo kwaye azinaziphene.

5. I-Thru-Hole Technology (THT)

Kumacandelo afuna iteknoloji yomngxuma (THT), icandelo lifakwa kwi-PCB's through-hole mhlawumbi ngesandla okanye ngokuzenzekelayo.

6. I-Soldering yamaza

I-PCB yecandelo elifakelweyo igqithiswa kumatshini we-wave soldering, kwaye umatshini we-wave soldering udibanisa inxalenye efakwe kwi-PCB ngokusebenzisa i-solder etyhidiweyo.

7. Uvavanyo lomsebenzi

Uvavanyo olusebenzayo lwenziwa kwi-PCB edityanisiweyo ukuqinisekisa ukuba isebenza ngokufanelekileyo kwisicelo esisiso. Uvavanyo olusebenzayo lungabandakanya uvavanyo lombane, uvavanyo lomqondiso, njl.

8. Uhlolo lokugqibela kunye noLawulo loMgangatho

Emva kokuba zonke iimvavanyo kunye neendibano zigqityiwe, uhlolo lokugqibela lwe-PCB lwenziwa ukuze kuqinisekiswe ukuba onke amacandelo afakwe ngokuchanekileyo, akukho naziphi na iziphene, kwaye ngokuhambelana neemfuno zoyilo kunye nemigangatho yomgangatho.

9. Ukupakishwa kunye nokuThunyelwa

Ekugqibeleni, i-PCB ephumelele ukukhangela umgangatho zipakishwe ukuqinisekisa ukuba azonakaliswa ngexesha lokuthuthwa kwaye zithunyelwe kubathengi.
