Niba ubajijwe ibara ikibaho cyumuzunguruko, ndizera ko reaction ya buriwese ari icyatsi. Tuvugishije ukuri, ibicuruzwa byinshi byarangiye mu nganda za PCB ni icyatsi. Ariko hamwe niterambere ryikoranabuhanga hamwe nibyifuzo byabakiriya, hagaragaye amabara atandukanye. Tugarutse ku nkomoko, kuki ikibaho ahanini ari icyatsi? Reka tubivugeho uyu munsi!
Igice cyicyatsi cyitwa kugurisha. Ibi bikoresho ni resin na pigment, igice cyicyatsi nicyatsi kibisi, ariko hamwe niterambere ryikoranabuhanga rigezweho, ryongerewe andi mabara menshi. Ntaho itandukaniye no gusiga irangi. Mbere yo kugurisha byacapwe ku kibaho cyumuzunguruko, kurwanya ibicuruzwa ni paste kandi bitemba. Nyuma yo gucapa ku kibaho cyumuzunguruko, resin irakomera kubera ubushyuhe hanyuma amaherezo “ikiza.” Intego yo gusudira yo kurwanya ni ukurinda ikibaho cyumuzunguruko kutagira ubushuhe, okiside hamwe n ivumbi. Ahantu honyine hatapfukiranwa nuwagurishije mubisanzwe bita padi kandi ikoreshwa mugurisha paste.
Muri rusange, duhitamo icyatsi kuko kidatera uburakari amaso, kandi ntabwo byoroshye kubakozi bashinzwe kubungabunga no kubungabunga bareba PCB igihe kirekire. Mugushushanya, amabara akunze gukoreshwa ni umuhondo, umukara numutuku. Amabara ashushanyije hejuru amaze gukorwa.
Indi mpamvu nuko ibara risanzwe rikoreshwa ari icyatsi, bityo uruganda rukagira irangi ryatsi risigara cyane, bityo igiciro cyamavuta kikaba gito. Ibi kandi ni ukubera ko iyo ukorera ikibaho cya PCB, insinga zitandukanye ziroroshye gutandukanya umweru, mugihe umukara numweru bigoye kubona. Kugirango utandukanye ibicuruzwa byayo amanota, buri ruganda rukoresha amabara abiri kugirango rutandukanye urwego rwohejuru ruva murwego rwo hasi. Kurugero, Asus, isosiyete ikora mudasobwa ya mudasobwa, ikibaho cyumuhondo kiri hasi, ikibaho ni impera ndende. Kwisubiraho kwa Yingtai ni murwego rwohejuru, kandi icyatsi kibisi ni gito.
1. Hariho ibimenyetso ku kibaho cyumuzunguruko: Intangiriro ya R ni résistoriste, intangiriro ya L ni coil inductor (mubisanzwe igiceri gikomeretsa impeta yicyuma, amazu amwe arafunze), intangiriro ya C ni capacitor (silindrike ndende, ipfunyitse muri plastiki, capacitori ya electrolytike hamwe na indentation ya cross, capacitori ya chip), andi maguru yombi ni diode, amaguru atatu ni tristoriste, kandi amaguru menshi ni umuzunguruko.
2, thyristor ikosora UR; Igenzura ryumuzingi rifite amashanyarazi akosora VC; Inverter UF; Guhindura UC; Inverter UI; Moteri M; Moteri idahwitse MA; Moteri ya moteri MS; Dc moteri MD; Moteri ya MW-ibikomere; Ikariso ya cage moteri MC; Umuyoboro w'amashanyarazi YM; Solenoid valve YV, nibindi
3, kwagura gusoma byongeweho igice cyigishushanyo kumurongo wibanze wumuzunguruko wibice bigize izina ryamakuru.
