Mavuto ena ndi momwe mungasamalire PCB plug limagwirira ndi zomwe anthu ambiri akufuna kudziwa, kotero nkhaniyi ikubweretserani inu chidziwitso ichi.

Choyamba, chifukwa cha vutoli

Ndikusintha kosalekeza kwa opanga ma PCB mwatsatanetsatane, opanga ma board ozungulira opangidwa ndi ma PCB akucheperachepera. Ponena za matabwa obowoleredwa mwamakina, kudzera m’mabowo okhala ndi mainchesi a 0.3mm ndi abwinobwino, ndipo 0.25mm kapena 0.15mm nawonso alibe malire. Pamene kabowoko kacheperachepera, kabowo kamakhala kotsekera. Pambuyo pobowola, mbaleyo nthawi zambiri imathyoka popanda kusweka. Kuyeza kwamagetsi sikungathe kuyeza maziko, ndipo pamapeto pake kumayenda mwa kasitomala. Pambuyo pakuwotcherera kutentha kwambiri, kugwedezeka kwamafuta komanso kusonkhana, kugwiritsa ntchito kumangokhala ku East Window. Yatsala pang’ono kulingalira za izo tsopano!

Ngati mungayambire pakupanga, mutha kugwiritsa ntchito mapulagi a dzenje limodzi ndi limodzi kuti mupewe kutsekeka koyipa. Iyi idzakhala njira yabwino yopititsira patsogolo khalidwe. Ine ndekha ndidayesera kukambirana za momwe mapulagi ena amagwirira ntchito, ndikupereka njira zina zothandiza zopewera kapena kuchepetsa kutsekeka koyipa.

Chachiwiri, santhulani mapulagi obowo oyipa munjira iliyonse

Tonse tikudziwa kuti opanga PCB ali ndi kubowola, degumming, plating mkuwa, plating, kukonza zithunzi, zithunzi plating ndi njira zina zazikulu mu PCB osindikizidwa dera kupanga ndi kukonza dzenje. Choncho, kusamvana kwa dzenje pulagi ndi inenso mmodzimmodzi. Yambitsani ndondomeko iliyonse.

pobowola

Mapulagi a dzenje omwe amayamba chifukwa cha kubowola makamaka amakhala ndi mitundu yotsatirayi, ndipo magawo azinthu akuwonetsedwa pachithunzichi.

mwachidule

Tinene mwachidule: Ngakhale zili choncho, munthu wanga samabowola lathyathyathya. Komabe, kunena zoona, kubowola akadali chimodzi mwazochitika zazikulu za mapulagi oipa. Malinga ndi kusanthula kwa ziwerengero za wolembayo, apeza kuti 35% ya mabowo alibe mkuwa, ndipo kubowola kwa dzenje komwe kumachitika chifukwa cha kubowola kumakhala koyipa kwambiri. Chifukwa chake, kuyang’anira kubowola ndiye cholinga chowongolera mapulagi. Ndikuganiza kuti mbali zotsatirazi ndizomwe zimawongolera:

1. Malinga ndi zotsatira zoyesera, m’malo modalira ambuye achikhalidwe kudalira chidziwitso cha kuphunzira kuti azindikire zomveka zoboola (mpeni pansipa ndi wothamanga kwambiri ndipo pulagi ndi yosavuta);

2. Kusintha kwa nthawi yobowola;

3. Onetsetsani kusonkhanitsa fumbi;

4. Ndikofunika kudziwa kuti kubowola kumabowola mabowo mu tepi kuti abweretse guluu mu dzenje, m’malo molowetsa tepiyo mu dzenje. Choncho, kubowola sikuyenera kubowoleredwa pa tepi nthawi iliyonse;

5. Kupanga njira zothandiza zodziwira tizibowo tosweka;

6. Opanga ambiri apanga ma pores opopera fumbi othamanga kwambiri komanso chithandizo chochotsa fumbi pambuyo pobowola, zomwe zitha kukhazikitsidwa;

7. The deburring ndondomeko pamaso mkuwa kumira ayenera akupanga kutsuka ndi mkulu-anzanu kutsuka (anzanu pamwamba 50KG/CM2).
