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 mubice bya PTH (Gucomeka Binyuze mu mwobo) na NPTH (Non Plating Binyuze mu mwobo) bisobekeranye mu mwobo, kandi turavuga ngo "tunyuze mu mwobo" kuko biva muburyo bumwe buva muruhande rumwe rwibibaho bijya kurundi, Mubyukuri, muri hiyongereyeho umwobo mu kibaho cyumuzunguruko, hari ibindi byobo bitanyuze ku kibaho cyumuzunguruko.
Amagambo ya PCB: binyuze mu mwobo, umwobo uhumye, umwobo washyinguwe.
1. Nigute dushobora gutandukanya PTH na NPTH binyuze mumyobo?
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 nkibizamini byo kuruhande rwisahani.
3. Ikoreshwa rya 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.
Ubundi buryo buto ugereranije na PTH, ubusanzwe bwitwa binyuze (umwobo wa conduction), bukoreshwa muguhuza no gutwara ikibaho cyumuzunguruko (PCB) hagati yibice bibiri cyangwa byinshi byumurongo wumuringa wumuringa, kubera ko PCB igizwe nibice byinshi byumuringa byegeranye, buri gice cya umuringa (umuringa) uzashyirwaho kaburimbo hamwe na layer ya insulation, ni ukuvuga ko umuringa udashobora gushyikirana, Guhuza ibimenyetso byayo biranyuze, niyo mpamvu byitwa "kunyura mu mwobo" mu gishinwa. Binyuze kuko ibyobo bitagaragara rwose bivuye hanze. Kuberako intego yo kunyuzamo ari ugukora umuringa wumuringa wuburyo butandukanye, bisaba amashanyarazi kugirango ukore, bityo unyuze nuburyo bwa PTH.
