Amakuru ku nganda: Ibintu by'ingenzi bigomba kwitabwaho ku bice bya SMT byizewe cyane muri sisitemu zigezweho za elegitoroniki

Mu bikoresho by'ikoranabuhanga byo muri iki gihe bifite ubucucike bwinshi kandi byihuta, ibikoresho byo gushyira hejuru (SMDs) byabaye ishingiro ry'igishushanyo mbonera cya none cy'uruziga. Uretse capacitors, resistor, inductors, EMI filters, na thermistors bigize urusobe rw'ibintu bidakora neza rutuma habaho ituze, imikorere yo kurwanya ingaruka mbi, no kuramba igihe kirekire mu nganda, imodoka, na semiconductor.

Ibice birwanya amashanyarazi ni byo bikoreshwa cyane, bitanga imipaka nyayo y'amashanyarazi, kugabanya voltage, no kugabanya ibimenyetso. Ibice birwanya amashanyarazi bifite imiterere myiza cyane bitanga ubushobozi bwo kwihanganira ibintu bike (nko hasi nka ± 0.1%), ubushyuhe buke (TCR), kandi bitanga ubuziranenge buhamye, bigatuma biba byiza mu gupima, gukoresha ibikoresho, no mu itumanaho. Ibice birwanya amashanyarazi, ku buryo butandukanye, bishyigikira ikwirakwizwa ry'ingufu nyinshi kandi bikunze gukoreshwa mu gucunga ingufu, kugenzura moteri, no mu nganda.

Utwuma dukoresha amashanyarazi (Chip inductors) n'utwuma dukoresha amashanyarazi (power inductors) bigira uruhare runini mu kubika ingufu, kuyungurura, no guhindura DC-DC. Hamwe n'ubudahangarwa buke bwa DC (DCR) n'umuyoboro w'amashanyarazi mwinshi, bigabanya neza igihombo cy'amashanyarazi kandi bikongera imikorere myiza yo guhindura. Utwuma dukoresha amashanyarazi menshi dushyigikira amashanyarazi ya radiyo (RF) n'imiyoboro y'amashanyarazi yihuta, bikomeza ubuziranenge bw'amajwi mu gihe bigabanya ingaruka mbi za electromagnetic.

Ibice byo guhosha EMI, birimo udupira tw’amapine, utumashini duto two gufunga amashanyarazi dukoreshwa mu buryo busanzwe, na filters zikoresha ikoranabuhanga riciriritse, birinda urusaku rw’inyuma n’ibintu bibangamira imbere mu kirere. Ibi bice ni ingenzi cyane mu gupakira ibikoresho bya semiconductor, ibikoresho by’ikoranabuhanga by’imodoka, n’ibikoresho by’ikoranabuhanga, aho uburyo bwo kohereza ibimenyetso buhamye bugira ingaruka zitaziguye ku mikorere n’umutekano w’ibicuruzwa.
Thermistors na varistors bitanga uburinzi bw'ingenzi ku bushyuhe bukabije n'ubushyuhe bukabije. Thermistors za Negative temperature coefficient (NTC) zigenzura impinduka z'ubushyuhe mu gihe nyacyo, zikarinda ubushyuhe bukabije mu ma modules afite ingufu nyinshi. Varistors zifata vuba voltages za surge, zikarinda chips na circuit boards ku miterere y'amashanyarazi no kwangirika kwa electrostatic.

Guhitamo ibice bigomba kwita ku bunini bw'ipaki, imikorere y'amashanyarazi, kwihanganira ibidukikije, n'amahame y'ubwirinzi nka AEC-Q200 ku binyabiziga. Ipaki nto (0402, 0201, 01005) zituma habaho ubucucike bwinshi bwa PCB, mu gihe ibice bikomeye bigumana ubusugire mu gihe cy'ubushyuhe bwinshi, ubushuhe, no guhindagurika.

Uko ikoranabuhanga rikomeza gutera imbere rigana ku gukora ibintu bito, gukoresha frequency nyinshi, no kumenya ubwenge, imikorere ya chip resistor, inductors, filters, n'ibice by'uburinzi bizakomeza kuba ingenzi mu miterere ya sisitemu. Guhitamo ibice bya SMT byiza kandi bihoraho ni ingenzi mu kunoza ubwizigirwa bw'ibicuruzwa, kugabanya igipimo cyo gutsindwa, no kongera ubushobozi bwo guhangana muri rusange.
