Countersunk makombazvinoboorwa pabhodhi redunhu netsono yemusoro wakadzikama kana banga regongo, asi hazvigone kuboorwa (kureva, semi kuburikidza nemakomba). The shanduko chikamu pakati pegomba rusvingo pa okunze / hombe gomba dhayamita uye gomba rusvingo padiki buri dhayamita inofambirana pcb pamusoro. Chikamu chinobatanidza makomba makuru uye maduku indege, kwete ndege yakarerekera.
Counterbore inonyanya kushandiswa kune simbi yedunhu mabhodhi, akadai sealuminium substrate uye mhangura substrate. Iyo simbi substrate ine yakakwirira mechanical simba uye haisi nyore kukuvadza PCB chimiro.
Iyo yekuburikidza-gomba, sezvinoreva zita, zvakare igomba, iro rinogona kupfuura nemuzvinhu kana zvinwiwa zvehukuru hwakakodzera,
Basa racho nderokuti:
a. Inoshandiswa kubatanidza uye inogona kugadzirwa kuita threaded through-buri.
b. Gadzira masilinda einjini dzepiston.
c. Muhupenyu, zvipfeko uye bhurugwa zvatinopfeka zvakare mienzaniso yekupfuura-gomba application
Iyo general crimping gole imhangura yakaiswa plug-in gomba.
Nekuda kweiyo yakakosha dhizaini yechikamu chetsoka, inogona kubatanidzwa zvakasimba negomba nekukakavadzana kwayo kwechimiro mushure mekupinzwa mugomba.
Zvakanakira kudzikisa wave soldering seti yewelding zvinhu zvakadaro; Kana maburi akadaro asina kusungirirwa pamagumo, zvichava nyore kutsiva zvikamu. Zvechokwadi, kudzokororwa kuchinjwa kuchakanganisa kuvimbika kwegomba.
Iyo element pini inoda maburi ekuchekeresa anowanzo kupihwa basa rekuwedzera, pane kuita shinda.
Zvimwe zvikamu zvinozoiswa welded zvakare gare gare kana zvimwe zvikamu zvave welded, nepo zvimwe zvisingabatirwe.
Counterbore yakakamurwa kuva mazita matatu:
1. Kunyatsonyura musoro wefastener mugomba renhanho rechikamu, chinonzi counterbore
2. Musoro wekusungirira hauna kunyura zvachose mugomba rechikamu, iro rinonzi countersink.
3. Musoro wechisungiso hauzonyura muchikamu chacho, uye chete gomba rine nzvimbo yakati sandara yechikamu rinonzi hove hole.
Musiyano pakati pegomba re countersunk uye countersunk hole nderokuti chikamu chepamusoro chegomba rebhoti chinodzokororwa zvakare: gomba rakadzivirirwa ndiro rakananga cylinder structure; Gomba re countersunk chimiro che 45 degree, chinotsvedzerera pane gomba rakanyura.
Iyo yepamusoro reming yegomba rebhoti inogona kugadzirisa musoro webhoti, kuitira kuti musoro webhaudhi usave wakakwirira kudarika nzvimbo yakapoteredza.
