Mu PCB mapangidwe, mtundu dzenje akhoza kugawidwa mu mabowo akhungu, kukwiriridwa mabowo ndi maenje chimbale, aliyense ali ndi zochitika zosiyanasiyana ntchito ndi ubwino, mabowo akhungu ndi kukwiriridwa mabowo makamaka ntchito kukwaniritsa kugwirizana magetsi pakati pa matabwa Mipikisano wosanjikiza, ndi chimbale. mabowo ndi anakonza ndi welded zigawo zikuluzikulu. Ngati mabowo akhungu ndi okwiriridwa amapangidwa pa bolodi la PCB, ndikofunikira kupanga mabowo a chimbale?
- Kodi maenje akhungu ndi maenje okwiriridwa ndi chiyani?
Bowo lakhungu ndi dzenje lomwe limagwirizanitsa pamwamba ndi mkati koma silimalowa pa bolodi lonse, pamene dzenje lokwiriridwa ndi dzenje lomwe limagwirizanitsa mkati ndipo siliwonekera kuchokera pamwamba. Maulendo awiriwa amagwiritsidwa ntchito makamaka kuzindikira kugwirizana kwa magetsi pakati pa matabwa amitundu yambiri ndikuwongolera kusakanikirana ndi kudalirika kwa bolodi la dera. Iwo akhoza kuchepetsa kuwoloka mizere pakati pa bolodi zigawo ndi kuchepetsa vuto la mawaya, potero kuwongolera ntchito wonse wa PCB.
- Kodi bowo la mbale ndi chiyani?
Mabowo a disc, omwe amadziwikanso kuti mabowo kapena ma perforations, ndi mabowo omwe amachoka mbali imodzi ya PCB kupita kwina. Amagwiritsidwa ntchito kwambiri pokonza ndi kuwotcherera zigawo, komanso kuzindikira kugwirizana kwa magetsi pakati pa bolodi la dera ndi zipangizo zakunja.
Bowo la chimbale limalola waya wa solder kapena pini kudutsa pa PCB kuti apange kugwirizana kwa magetsi ndi solder pad kumbali inayo, motero kumaliza kuyika kwa chigawocho ndi kugwirizana kwa dera.
- Momwe mungasankhire mabowo akhungu / okwiriridwa ndi mabowo a PAD?
Ngakhale mabowo akhungu ndi mabowo okwiriridwa amatha kukwaniritsa kulumikizana kwamagetsi pakati pa matabwa amitundu yambiri, sangathe m'malo mwa mabowo a disc.
Choyamba, dzenje la chimbale lili ndi mwayi wapadera pakukonzekera chigawo ndi kuwotcherera, zomwe zingatsimikizire kukhazikika ndi kudalirika kwa zigawozo.
Chachiwiri, pamabwalo ena omwe amafunika kulumikizidwa ndi zida zakunja, mabowo a disk ndi ofunikira.
Kuphatikiza apo, m'mabwalo ena ovuta, mabowo akhungu, mabowo okwiriridwa, ndi mabowo a disc angafunikire kugwiritsidwa ntchito nthawi imodzi kuti akwaniritse zofunikira zosiyanasiyana zolumikizira.
