Kodi kusiyanitsa pakati pa dzenje, akhungu kudzera ndi kukwiriridwa kudzera mu PCB?
Pakupanga ndi kupanga kwa PCB, nthawi zambiri timagwiritsa ntchito dzenje, akhungu / okwiriridwa kudzera pakukwaniritsa zosowa zamapangidwe ndi magwiridwe antchito. Ndiye pali kusiyana kotani pakati pawo?
1.Kupyolera mu dzenje
A through hole ndi mtundu wosavuta komanso wamba wamabowo mu PCB. Amapangidwa pobowola dzenje mu PCB (wosanjikiza pamwamba mpaka pansi) ndikudzaza ndi zinthu zopangira (monga mkuwa). Nthawi zambiri amagwiritsidwa ntchito kulumikiza mabwalo pamagawo osiyanasiyana kuti apereke kulumikizana kwamagetsi ndi chithandizo chamakina.
Mtengo wodutsa dzenje ndi wotsika mtengo, koma pamapangidwe apamwamba kwambiri a HDI, popeza danga la bolodi ndilofunika kwambiri, kapangidwe ka dzenje ndi kowononga.
2.Akhungu kudzera
Kusaona kumangofanana ndi dzenje, koma osawona amangodutsa pa PCB. Imatsogolera pamwamba wosanjikiza mkati popanda kudutsa PCB. Nthawi zambiri ntchito kulumikiza madera pakati pamwamba ndi mkati zigawo, oyenera Mipikisano wosanjikiza PCB ndi malo ochepa. Njira yopangira akhungu kudzera m'njira yovuta kwambiri. Kulephera kusamala pakubowola kuya kungayambitse zovuta mu electroplating m'mabowo. Choncho, zigawo zozungulira zomwe ziyenera kugwirizanitsidwa zimatha kugwedezeka poyamba pamene zili zosiyana siyana, ndiyeno zonse zimagwirizanitsidwa. Komabe, kugwiritsa ntchito njirayi kumafuna kuyika kolondola komanso kulinganiza zida. Chifukwa chake, njira yakhungu ndiyokwera mtengo kwambiri kuposa pobowo.
3.Kukwiriridwa kudzera
M'manda vias zobisika mkati aliyense wosanjikiza wa PCB ndi kulumikiza zigawo ziwiri kapena kuposa zamkati PCB. Iwo sawoneka pamwamba ndi pansi zigawo. Nthawi zambiri amakhala oyenera matabwa ozungulira a HDI okwera kwambiri kuti awonjezere malo ogwiritsira ntchito zigawo zina zadera. Pakuti kupanga vias m'manda, pobowola ntchito angathe kuchitidwa pa munthu dera zigawo choyamba. Wosanjikiza wamkati poyamba amamangiriridwa pang'ono ndiyeno electroplated, ndiyeno onse amamangidwa. Chifukwa njira yogwirira ntchitoyo ndi yolemetsa kwambiri kuposa yoyambirira kudzera pabowo ndi khungu, mtengo wake ndi wokwera mtengo.
Malangizo:
Mtengo: Kupyolera mu dzenje＜Wakhungu kudzera＜Kukwiriridwa kudzera
Kugwiritsa ntchito danga: kudzera mu dzenje ＜khungu kudzera ＜kukwiriridwa kudzera
Kuvuta kwa ntchito: kupyola dzenje ＜khungu kudzera mu＜kukwiriridwa kudzera
Richpcba imapatsa makasitomala ntchito za PCB + SMT zokhala ndi "mtengo wabwino kwambiri, wapamwamba kwambiri, komanso kutumiza mwachangu", zitsanzo zathunthu + kupanga misa, ndikuthetsa zofunikira zamakasitomala za PCBA imodzi. Zogulitsazi zimagwiritsidwa ntchito kwambiri muluntha lochita kupanga, zida, zida zoyankhulirana, kusungirako mphamvu za photovoltaic, zamagetsi zamagalimoto ndi magawo ena.
