Zitha kuwonedwa kuti pali mabowo ambiri akuluakulu ndi ang'onoang'ono mu bolodi la dera, ndipo zikhoza kupezeka kuti pali mabowo ambiri wandiweyani, ndipo dzenje lililonse limapangidwira cholinga chake. Mabowowa akhoza kugawidwa mu PTH (Plating Through Hole) ndi NPTH (Non Plating Through Hole) plating kudzera dzenje, ndipo timati "kupyolera mu dzenje" chifukwa kwenikweni amapita mbali imodzi ya bolodi ina, Ndipotu, kuwonjezera pa bowo mu bolodi dera, pali mabowo ena amene sali kudzera gulu dera.
Mawu a PCB: kupyola dzenje, dzenje lakhungu, dzenje lokwiriridwa.
1. Kodi mungasiyanitse bwanji PTH ndi NPTH m'mabowo?
Ikhoza kuweruzidwa ngati pali zizindikiro zowala za electroplating pa khoma la dzenje. Bowo lomwe lili ndi ma electroplating ndi PTH, ndipo dzenje lopanda ma electroplating ndi NPTH. Monga momwe chithunzi chili pansipa:
2. TheUMtengo wapatali wa magawo NPTH
Zimapezeka kuti kutsegula kwa NPTH nthawi zambiri kumakhala kokulirapo kuposa PTH, chifukwa NPTH imagwiritsidwa ntchito ngati screw screw, ndipo ena amagwiritsidwa ntchito kukhazikitsa zolumikizira kunja kwa cholumikizira chokhazikika. Kuphatikiza apo, zina zitha kugwiritsidwa ntchito ngati mayeso oyeserera kumbali ya mbale.
3. Kugwiritsa Ntchito PTH, Via ndi Chiyani?
Nthawi zambiri, mabowo a PTH pa board board amagwiritsidwa ntchito m'njira ziwiri. Imodzi imagwiritsidwa ntchito kuwotcherera mapazi a zida zachikhalidwe za DIP. Kubowo kwa mabowowa kuyenera kukhala kokulirapo kuposa kutalika kwa miyendo yowotcherera ya zigawozo, kuti magawowo alowe m'mabowowo.
PTH ina yaing'ono, yomwe nthawi zambiri imatchedwa kudzera (bowo la conduction), imagwiritsidwa ntchito kulumikiza ndi kuyendetsa bolodi (PCB) pakati pa zigawo ziwiri kapena zingapo za mzere wamkuwa wa zojambulazo, chifukwa PCB imapangidwa ndi zigawo zambiri zamkuwa zowunjika, wosanjikiza uliwonse wamkuwa (mkuwa) udzapakidwa ndi wosanjikiza wa insulation, ndiye kuti, wosanjikiza mkuwa sungathe kulumikizana ndi wina ndi mnzake kudzera mu dzenje. Chitchainizi. Kudzera chifukwa mabowo ndi wosaoneka kwathunthu kuchokera kunja. Chifukwa cholinga cha via ndikupangira zojambula zamkuwa za zigawo zosiyanasiyana, zimafunika kuti electroplating ichitike, kotero kudzera ndi mtundu wa PTH.
