Sei zvakakosha kuchengeta PCB yako yakachena?

Paunenge uchinetsa kusashanda kana kusaita zvakanaka maseketi, mainjiniya anogona kazhinji kumhanyisa masimulation kana mamwe maturusi ekuongorora kuti atarise dunhu padanho rehurongwa. Kana nzira idzi dzikasagadzirisa dambudziko, kunyangwe mainjiniya akanakisa anogona kugumburwa, kuvhiringidzika, kana kuvhiringika. Ndakasanganawo nemarwadzo aya. Kuti udzivise kurova magumo akafanana, rega ndikuzivise kune yakapfava asi yakakosha matipi: ichengetedze yakachena!

Ndinorevei kana zvakadaro? Izvo zvakati, zvimwe zvinhu zvinoshandiswa panguva yePCB gungano kana kugadziridzwa zvinogona kukonzera akakomba edunhu matambudziko kana PCB ikasachengetwa yakachena. Imwe yezvinetso zvinowanzoitika neichi chiitiko ndeye flux.

 

Mufananidzo 1 unoratidza PCB ine kuwanda kwehuwandu hwekuyerera kwakasara.

Flux ikemikari inoshandiswa kubatsira mukutengesa zvinhu kuPCB. Zvinosuruvarisa kuti, kana isina kubviswa mushure mekutengesa, flux inogona kushatisa iyo yekumusoro insulation kuramba kwePCB, zvichikonzera kuderera kwakanyanya mukuita kwedunhu mukuita!

Mufananidzo 2 idunhu rekuyedza randaishandisa kuratidza mhedzisiro yekusvibiswa kweflux. Iyo yakadzikama Wheatstone bhiriji network yakavhurwa ne 2.5V referensi voltage inotevedzera yakakwira-impedance bhiriji sensor. Iyo yekusiyanisa bhiriji sensor inobuda VIN + - VIN- inogona kubatana neINA333 nekuwana kwe101V/V. Munyika yakanaka, sezvo bhiriji riri mukuenzana, VIN+ - VIN- = 0V. Asi kusvibiswa kweflux kunogona kukonzera iyo chaiyo bhiriji sensor voltage kuti ifambe zvishoma nezvishoma nekufamba kwenguva.

Mumuedzo uyu, mushure megungano, ndakanyorawo shanduko muVIN- uye VOUT kweawa imwe mushure memazinga akasiyana ekuchenesa:

1.Kwete kuchena;

2.Kuchenesa nemaoko uye mhepo yakaoma;

3.Ultrasonic kuchenesa, kuomeswa kwemhepo, kubika.

Sezvinoonekwa muMufananidzo 3, kusvibiswa kweflux kune kukanganisa kwakanyanya pakubuda kweiyo sensor yebhiriji. Pasina kuchenesa kana kucheneswa nemaoko, bhiriji sensor voltage haina kumbosvika kune yaitarisirwa voltage yeinenge VREF/2, kunyangwe mushure meawa imwe yekudzikamisa nguva. Pamusoro pezvo, mabhodhi edunhu asina kuchena anoratidzawo kuunganidzwa kwakakura kwekunze kweruzha. Mushure mekuchenesa nekugeza kwe ultrasonic uye kuomesa zvachose, bhiriji sensor voltage yaive yakasimba.

Tichitarisa kubuda kwemagetsi eINA333, isu tinoramba tichiona kuderedzwa kwekuita kunokonzerwa nekucheneswa kusina kunaka.

1.Mabhodhi asina kuchena airatidza zvikanganiso zveDC, nguva dzekugara kwenguva refu, uye pikicha yakaoma yekunze yeruzha;

2.Manually kucheneswa redunhu mabhodhi vanoratidza zvinoshamisa yakaderera zvikuru frequency ruzha. Ndakazowana chikonzero - yaive air conditioning loop mukati menzvimbo yekuyedza!

3.Sezvinotarisirwa, mapuranga akacheneswa uye akaomeswa zvakanaka akanyatsoita zvakanaka, pasina kudonha kunoitika chero panguva yekuedzwa.

 

Muchidimbu, kucheneswa kwakashata kweflux kunogona kukonzera kuderera kwekuita kwakanyanya, kunyanya mumaseketi eDC. Sezvineiwo ese maPCB akaunganidzwa nemaoko kana akagadziridzwa, iva nechokwadi chekushandisa ultrasonic bath (kana nzira yakafanana) pakuchenesa kwekupedzisira. Bika iyo yakaunganidzwa uye yakacheneswa PCB pane tembiricha yakakwira zvishoma kuti ubvise chero hunyoro hwasara mushure mekuoma kwemhepo uchishandisa air compressor. Kazhinji tinobika pa 70 ° C kwemaminitsi gumi.

Iri rakareruka "richengetedze rakachena" zano rinofanirwa kukubatsira iwe kushandisa yakaderera nguva yekugadzirisa uye yakawanda nguva kugadzira makuru, epamusoro-chaiyo maseketi!

 

Xuange Electronicsyakazvipira kuve inotungamira pasi rose kugadzira magineti zvikamu, ichipa kwete chete zvakajairwa zvigadzirwa asiwo yakagadziridzwa masevhisi ekugadzira kuitira kuti vatengi vawane mhedzisiro yakanaka. Zvese zvinoshandiswa muzvigadzirwa zvakapfuura UL / CEcertificationuye vakaedzwa zvakasimba uye kuongororwa vasati vatumirwa kuti vave nechokwadi chehutano hwakagadzikana uye kusimbisa vatengi. Ishamwari yakavimbika yenguva refu yevagadziri vemagetsi makuru emagetsi!
Pamibvunzo yechigadzirwa, ndapota tarisa iyochigadzirwa peji, unogamuchirwawotaura nesukuburikidza neruzivo rwekusangana pazasi, isu tichakupindura iwe mukati me24.
