Birashobora kugaragara ko hariho imyobo minini nini nini nini mu kibaho cyumuzunguruko, kandi ushobora gusanga hari ibyobo byinshi byuzuye, kandi buri mwobo wagenewe intego yabyo. Ibyo byobo birashobora kugabanywa cyane muri PTH (Gucisha mu mwobo) na NPTH (Non Plating Binyuze mu mwobo) bisobekeranye mu mwobo, kandi turavuga ngo "tunyuze mu mwobo" kuko byukuri biva mu rubavu rumwe rujya ku rundi, Mubyukuri, usibye kunyura mu mwobo uri mu kibaho cy’umuzunguruko, hari ibindi byobo bitanyuze ku kibaho cy’umuzunguruko.
Amagambo ya PCB: binyuze mu mwobo, umwobo uhumye, umwobo washyinguwe.
1.Ni gute dushobora gutandukanya PTH na NPTH binyuze mu mwobo?
Irashobora gucirwa urubanza niba hari ibimenyetso byerekana amashanyarazi kurukuta. Umwobo ufite ibimenyetso bya electroplating ni PTH, naho umwobo udafite ibimenyetso bya electroplating ni NPTH. Nkuko bigaragara ku ishusho hepfo:
2. TheUumunyabwenge wa NPTH
Byagaragaye ko aperture ya NPTH mubusanzwe iba nini kuruta PTH, kubera ko NPTH ikoreshwa cyane nkumugozi wo gufunga, kandi bimwe bikoreshwa mugushiraho amahuza amwe hanze ya connexion yagenwe. Mubyongeyeho, bimwe bizakoreshwa nkibikoresho byo kugerageza kuruhande rwisahani.
3. Gukoresha PTH, Binyuze iki?
Mubisanzwe, PTH umwobo kurubaho ruzunguruka zikoreshwa muburyo bubiri. Imwe ikoreshwa mugusudira ibirenge bya DIP gakondo. Ubushuhe bwibi byobo bugomba kuba bunini kurenza diameter ya metero yo gusudira yibice, kugirango ibice byinjizwe mu mwobo.
Ikindi kintu gito ugereranije na PTH, gikunze kwitwa binyuze (umwobo wa conduction), gikoreshwa muguhuza no gutwara ikibaho cyumuzunguruko (PCB) hagati yibice bibiri cyangwa byinshi byumurongo wumuringa wumuringa, kubera ko PCB igizwe nibice byinshi byumuringa byegeranijwe, buri cyuma cyumuringa (umuringa) kizashyirwaho kaburimbo cyumubyimba, ni ukuvuga ko umuringa udashobora gushyikirana nuwitwa, ni ukubera ko kunyura mubimenyetso byacyo ari byo. Binyuze kuko ibyobo bitagaragara rwose bivuye hanze. Kuberako intego yo kunyuramo ari ugukora umuringa wumuringa wibice bitandukanye, bisaba amashanyarazi gukora, bityo binyuze muburyo bumwe bwa PTH.
