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 amatha kugawidwa kukhala PTH (Plating Through Hole) ndi NPTH (Non Plating Through Hole) kupyola mu dzenje, ndipo timati "kupyolera mu dzenje" chifukwa amachokera mbali imodzi ya bolodi kupita ku ina, Ndipotu, mu dzenje. kuwonjezera pa dzenje mu bolodi dera, pali mabowo ena amene si kudzera gulu gulu.
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 loyendetsa), imagwiritsidwa ntchito polumikiza ndi kuyendetsa bolodi (PCB) pakati pa zigawo ziwiri kapena zingapo za mzere wamkuwa wa zojambulazo, chifukwa PCB imapangidwa ndi zigawo zambiri zamkuwa zowunjika, mkuwa (mkuwa) udzapangidwa ndi wosanjikiza wa kutchinjiriza wosanjikiza, ndiko kunena kuti, wosanjikiza mkuwa sangathe kulankhulana wina ndi mzake, Kulumikizana ndi chizindikiro chake ndi kudzera, chifukwa chake amatchedwa "kudutsa dzenje" mu Chinese. 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.
