Taxaddarrada qalliinka alxanka ee guddiga laba dhinac pcb | YMSPCB

Marka la barbardhigo guddiga wareegga hal-dhinac ah, guddiga kumbuyuutarrada laba-geesoodka ah wuxuu leeyahay cufnaanta fiilooyinka badan iyo aperture.Layer - to - lakabka isku xirnaanta waxay kuxirantahay godadka metallized, oo si toos ah ula xiriira kalsoonida guddiga wareegga daabacan. , sida qashinka burushka, dambaska volcanic, iyo wixii la mid ah, mar hadhay godka gudihiisa, waxay ka dhigi doontaa kiimikada saxanka naxaasta, electroplating luminta naxaasta.

Si loo hubiyo saameynta ku-kalsoonaanta dariiqa ee guddiga wareegga laba-geesoodka ah, godka isku xiraya guddiga waa in lagu xiraa nooca siligga marka hore, iyo qaybta soo-baxa ee siligga siligga isku xiraya waa in la gooyaa, si aan loo mudin gacanta hawl wadeenka. Tani waa shaqada diyaarinta ee xariijinta iskuxirka guddiga.

Sidaas, waxa dhibaatooyin waa in fiiro gaar ah in alxanka guddiga PCB dhinac dhinac

1. Qalabka u baahan qaabeynta, waa inay raacdaa shuruudaha habka wax lagu sawirayo, marka hore qaabeynta iyo ka dib bareeska.

2. Qaabaynta ka dib, nooca diode waa inuu wajihi doonaa, dhererka labada biinna waa inuusan iswaafaqsaneyn.

3. Qalabka leh shuruudaha kala-baxa, waa in la ogaadaa in kala-goynta aan la gelin doonin jihada ka soo horjeedda. Janjeer muuqda looma oggolaan doono aaladaha toosan ama jiifka ka dib gelinta ka dib.

4. Awoodda birta korantada korontada waa 25 ~ 40W, heerkulka madaxa birta korantada korontada waa in lagu xakameeyaa 242 ℃ ama sidaas, waqtiga alxanka waa in lagu xakameeyaa 3 ~ 4 ilbiriqsi.

5, alxanka guud ahaan marka loo eego aaladda kor ilaa sare, laga bilaabo gudaha ilaa banaanka mabda'a alxanka si uu u shaqeeyo, waqtiga alxanka si loo barto, waqti aad u dheer ayaa noqon doona qalab kulul, sidoo kale silig naxaas kulul leh oo saxan saxan naxaas leh .

6, maxaa yeelay waa alxanka laba-geesoodka ah, sidaa darteed waa inuu sidoo kale sameeyaa qaab-dhismeed lagu dhejiyo guddiga wareegga, ujeedku maahan inuu ku riixo qalabka hoose.

7. Ka dib marka la dhammeeyo alxamida, kormeer dhammaystiran ayaa la samayn doonaa si loo hubiyo meelaha ay ku yaalliin waxyaalaha ka soo daadanaya iyo weligood. Xaqiijinta ka dib, yaree biinanka qalabka aan loo baahnayn oo u oggolow inay ku sii socdaan hawsha xigta.

8. Hawlgallada gaarka ahi waa inay si adag u raacaan heerarka geeddi-socodka ee ku habboon si loo hubiyo tayada alxanka.

Waxyaabaha kor ku xusan waa taxaddarrada hawlgalka alxanka alxanka guddiga laba-geesoodka ah. Haddii aadan ogeyn, waxaad la tashan kartaa shirkadda - Yongmingsheng Circuit board Company waqti kasta.
