Chala Chagolide: (Chala Chagolide kapena Cholumikizira Chakumphepete) Ikani mbali imodzi ya PCB bolodi mu cholumikizira khadi kagawo, ndi ntchito cholumikizira pini monga kotulukira kwa bolodi pcb kulumikiza kunja, kuti pad kapena mkuwa khungu kukhudzana ndi pini pa malo lolingana Kuti akwaniritse cholinga conduction, ndi faifi tambala. -golide atakutidwa pa pad iyi kapena chikopa chamkuwa cha pcb board, chimatchedwa chala chagolide chifukwa chimakhala ngati chala. Golide adasankhidwa chifukwa chapamwamba kwambiri komanso kukana kwa okosijeni. Abrasion resistance. Komabe, chifukwa cha mtengo wokwera kwambiri wa golidi, amagwiritsidwa ntchito popangira golide pang’ono monga zala zagolide.

Gulu la chala chagolide ndi chizindikiritso, mawonekedwe

Magulu achinyengo: chinyengo wamba (zala zonyowa), zanyengo zazitali ndi zazifupi (ndiko kuti, zachinyengo zosagwirizana), ndi zachinyengo zamagulu (zachinyengo zapakatikati).

1. Zala zagolide zokhazikika (zala zootcha): mapepala amakona anayi okhala ndi utali wofanana ndi m’lifupi amakonzedwa bwino m’mphepete mwa bolodi. Chithunzi chotsatirachi chikuwonetsa: makadi a maukonde, makadi ojambula zithunzi ndi mitundu ina ya zinthu zakuthupi, ndi zala zambiri zagolide. Ma mbale ang’onoang’ono amakhala ndi zala zochepa zagolide.

2. Zala zazitali ndi zazifupi zagolide (ie zala zagolide zosagwirizana): mapepala amakona anayi okhala ndi utali wosiyana m’mphepete mwa bolodi 3. Zala zagolide zogawanika (zala zagolide zapakatikati): mapepala amakona anayi okhala ndi utali wosiyana m’mphepete mwa bolodi, ndi kulumikiza gawo lakutsogolo.

Palibe chimango ndi zilembo, ndipo nthawi zambiri imakhala zenera lotsegulira chigoba cha solder. Mawonekedwe ambiri amakhala ndi grooves. Chala chagolide chinatuluka m’mphepete mwa bolodi kapena pafupi ndi m’mphepete mwa bolodi. Mapulani ena amakhala ndi zala zagolide kumbali zonse ziwiri. Zala za golide wamba zili ndi mbali zonse ziwiri, ndipo ma pcb ena amakhala ndi zala zagolide za mbali imodzi. Zala zina zagolide zimakhala ndi muzu umodzi waukulu.

Pakadali pano, njira yomwe imagwiritsidwa ntchito kwambiri pakukondera zala zagolide imaphatikizapo mitundu iwiri iyi:

Chimodzi ndicho kutsogolera kuchokera kumapeto kwa chala chagolide ngati waya wokutidwa ndi golide. Pambuyo kupaka golide kumalizidwa, kutsogolera kumachotsedwa ndi mphero kapena etching. Komabe, mankhwala opangidwa ndi njira yotereyi adzakhala ndi zotsalira zotsogolera kuzungulira zala za golidi, zomwe zimapangitsa kuti pakhale mkuwa, zomwe sizingakwaniritse zofunikira kuti musalole kuwonekera kwa mkuwa.

Chinacho ndicho kutsogolera mawaya osati kuchokera ku zala za golide, koma kuchokera ku zigawo zamkati kapena zakunja za bolodi lozungulira zomwe zimagwirizanitsidwa ndi zala za golide kuti zikwaniritse golide wa zala zagolide, potero kupewa kukhudzana ndi mkuwa kuzungulira zala zagolide. Komabe, pamene kachulukidwe ka bolodi la dera ndipamwamba kwambiri ndipo dera ndi wandiweyani kwambiri, njirayi sangathe kupanga zitsogozo mu dera wosanjikiza; Komanso, njirayi ilibe mphamvu kwa zala zapadera za golide (ndiko kuti, zala za golide sizikugwirizana ndi dera).
