Pali mitundu yambiri ya matabwa PCB dera pa msika, ndipo n'zovuta kusiyanitsa zabwino ndi zoipa khalidwe.Pankhani imeneyi, pali njira zingapo zodziwira khalidwe la matabwa a dera PCB.

Kungoyang'ana maonekedwe

1. Maonekedwe a weld seam

Popeza pali mbali zambiri pa bolodi PCB dera, ngati kuwotcherera si zabwino, mbali bolodi dera mosavuta kugwa, kukhudza kwambiri kuwotcherera khalidwe ndi maonekedwe a bolodi dera, choncho n'kofunika kwambiri kuwotcherera olimba.

2. Malamulo okhazikika a kukula ndi makulidwe

Popeza matabwa ozungulira PCB ali makulidwe osiyana poyerekeza matabwa muyezo dera, owerenga akhoza kuyeza ndi kufufuza malinga ndi zosowa zawo.

3. Kuwala ndi mtundu

Kawirikawiri kunja PCB dera bolodi yokutidwa ndi inki kwa kutchinjiriza.Ngati mtundu wa bolodi suli wowala ndipo pali inki yocheperako, zikutanthauza kuti bolodi lotsekera palokha silili bwino.

Chiweruzo kuchokera ku mbale zakuthupi

1. Makatoni wamba a HB ndi otsika mtengo komanso osavuta kupunduka ndikuswa.Itha kupangidwa kukhala gulu limodzi.Pamwamba pa chigawocho ndi mdima wachikasu mu mtundu ndipo ali ndi fungo loipa.Chophimba chamkuwa ndi cholimba komanso chowonda.

2. Ma board a 94V0 a mbali imodzi ndi CEM-1 ndi okwera mtengo kuposa makatoni.Mtundu wa chigawocho pamwamba ndi kuwala chikasu.Amagwiritsidwa ntchito makamaka kwa matabwa a mafakitale ndi matabwa amphamvu omwe ali ndi zofunikira zotetezera moto.

3. Fiberglass board ili ndi mtengo wapamwamba, mphamvu yabwino, ndipo ndi yobiriwira mbali zonse.Kwenikweni, matabwa ambiri PCB dera amapangidwa ndi nkhaniyi.Chophimba chamkuwa chikhoza kukhala cholondola komanso chabwino, koma bolodi la unit ndilolemera kwambiri.Ziribe kanthu mtundu wa inki kusindikizidwa pa bolodi dera PCB, ayenera kukhala yosalala ndi lathyathyathya, ndipo pasakhale mizere zabodza, poyera mkuwa kapena kubwebweta.
