Kuki ari ngombwa kugira isuku PCB yawe?

Mugihe cyo gukemura ibibazo bidakorwa cyangwa bidakora neza, injeniyeri zirashobora gukoresha simulation cyangwa ibindi bikoresho byo gusesengura kugirango tuzirikane uruziga kurwego rwibishushanyo. Niba ubu buryo budakemuye ikibazo, naba injeniyeri beza barashobora gutsitara, gucika intege, cyangwa urujijo. Nanjye nariboneye ubu bubabare. Kugira ngo wirinde gukubita impera zisa, reka nkumenyeshe inama yoroshye ariko ikomeye: komeza isuku!

Ndashaka kuvuga iki? Ibyo byavuzwe, ibikoresho bimwe bikoreshwa mugihe cyo guterana kwa PCB cyangwa guhindura bishobora gutera ibibazo bikomeye byimikorere yumuzunguruko niba PCB idakozwe neza. Kimwe mubibazo bikunze kugaragara kuri iki kintu ni flux.

 

Igishushanyo 1 kirerekana PCB ifite ubwinshi bwibisigisigi bya flux.

Flux ni imiti ikoreshwa mugufasha kugurisha PCB. Ikibabaje ariko, niba bidakuweho nyuma yo kugurisha, flux irashobora gutesha agaciro ubukana bwimiterere ya PCB, bigatera kwangirika gukomeye mubikorwa byumuzunguruko mubikorwa!

Igishushanyo 2 ni ikizamini cyizamini nakoresheje kugirango ngaragaze ibisubizo byanduye. Umuyoboro uringaniye wa Wheatstone ukoreshwa na voltage ya 2.5V yerekana kwigana sensor-ikiraro kinini. Ikiraro gitandukanya sensor isohora VIN + - VIN- irashobora guhuzwa na INA333 hamwe ninyungu ya 101V / V. Mwisi yisi nziza, kubera ko ikiraro kiri muburinganire, VIN + - VIN- = 0V. Ariko kwanduza flux birashobora gutuma ikiraro nyacyo cya sensor ya voltage igenda gahoro gahoro mugihe.

Muri iki kizamini, nyuma yo guterana, nanditse kandi impinduka muri VIN- na VOUT kumasaha imwe nyuma yinzego zitandukanye zogusukura:

1.Ntabwo bisukuye;

2.Kora intoki n'umwuka byumye;

3.Isuku ya ultrasonic, kumisha umwuka, guteka.

Nkuko bigaragara ku gishushanyo cya 3, kwanduza flux bigira ingaruka zikomeye kumikorere yimikorere yikiraro. Hatabayeho gusukura cyangwa gusukura intoki, voltage sensor yikiraro ntabwo yigeze igera kuri voltage iteganijwe hafi ya VREF / 2, nubwo nyuma yisaha imwe yo guhagarara. Byongeye kandi, imbaho ​​zanduye zanduye nazo zigaragaza urusaku rukomeye rwo hanze. Nyuma yo koza nogesheje ultrasonic no gukama burundu, voltage sensor yikiraro yari ikomeye.

Urebye ibisohoka voltage ya INA333, dukomeje kubona imikorere mibi iterwa no gukora isuku idakwiye.

1.Ibibaho bidasukuye byerekanaga amakosa ya DC, igihe kirekire cyo gutuza, hamwe na pikipiki ikomeye yo hanze;

2.Intoki zasukuwe nintoki zerekana urusaku rudasanzwe cyane. Amaherezo nabonye icyabiteye - ni icyuma gikonjesha imbere yikizamini!

3. Nkuko byari byitezwe, imbaho ​​zisukuye neza kandi zumye zakoze neza cyane, nta drift ibaho mugihe icyo aricyo cyose mugihe cyizamini.

 

Muri make, isuku ya flux idakwiye irashobora gutera imikorere mibi cyane, cyane cyane mumashanyarazi ya DC. Kimwe na PCBs zose ziteranijwe cyangwa zahinduwe, menya neza ko ukoresha ubwogero bwa ultrasonic (cyangwa uburyo busa) kugirango usukure bwa nyuma. Guteka PCB yateranijwe kandi isukuye ubushyuhe burenze gato kugirango ukureho ubuhehere busigaye nyuma yo gukama umwuka ukoresheje compressor de air. Mubisanzwe duteka kuri 70 ° C muminota 10.

Iyi nama yoroshye "komeza isuku" igomba kugufasha kumara umwanya muto wo gukemura ibibazo hamwe nigihe kinini cyo gushushanya imirongo ikomeye, yuzuye neza!

 

Xuange Electronicsyiyemeje kuba iyambere ku isi ikora ibintu bya magneti, idatanga ibicuruzwa bisanzwe gusa ahubwo inatanga serivisi zishushanyije kugirango abakiriya babone ibisubizo byiza. Ibikoresho byose bikoreshwa mubicuruzwa byatsinze UL / CEicyemezokandi barageragejwe cyane kandi bagenzurwa mbere yo koherezwa kugirango barebe neza kandi bijeze abakiriya. Numufatanyabikorwa wizewe wigihe kirekire mubikorwa byingenzi bitanga amashanyarazi!
Kubibazo byibicuruzwa, nyamuneka rebaurupapuro rwibicuruzwa, urahawe ikazetwandikireukoresheje amakuru y'itumanaho hepfo, tuzagusubiza muri 24.
