Imikhiqizo yomsindo idinga ukunakwa ekungcoleni nasekubekweni kwayo ngomshini. Imbobo yemakrofoni noma ingxenye ye-acoustic ingathinteka yizinsalela, udoti noma indawo engafanele ye-gasket. Izidingo eziqondile zokuphatha nokuhlola kufanele zivela ekuchazweni kwenhlangano yekhasimende.

Ukuhlolwa kwezinga lebhodi kungaqinisekisa ukubekwa kanye nokushiselwa, kodwa ukwamukelwa kwe-acoustic kufanele kusebenzise indlela yokuhlola umsindo noma i-fixture echazwe yikhasimende. Lokhu kugcina ukuhlolwa kokukhiqiza kulinganiselwe futhi kuphindaphindwa.

Uma irekhoda isebenzisa ibhodi yemakrofoni exhunyiwe, faka umndeni wesixhumi, ikhebula noma imininingwane ye-FPC kanye nomdwebo wokuhlanganiswa ku-RFQ.

Ukuhlolwa kokukhiqiza: iphasi kagesi ayifani nephasi yomsindo

Ukuhlolwa kokukhiqiza okunenjongo kungafaka phakathi ukuhlela, ukusetshenziswa kwamandla, ukufinyelela kwisitoreji, ukufaka imakrofoni, ukuqopha, ukudlala kanye nokuphathwa kwamafayela kuye ngomkhiqizo. Imikhawulo eqondile yempendulo yemvamisa, ukuzwela noma umsindo kufanele inikezwe yi-OEM.

Uma irekhoda iklanyelwe imodi ethile yokurekhoda, ukuhlolwa kufanele kusebenzise leyo modi kunokuhlola amandla okuvamile. Ifektri ingenza ukuhlolwa kokwamukelwa okuchazwe yikhasimende ngaphandle kokufaka icala lokufaneleka okuphelele kwe-acoustic komkhiqizo.

I-Highleap isekela ukuhlolwa okusebenzayo njengengxenye yezinsizakalo zokuhlanganisa i-PCB.

Umjikelezo wokuphila we-BOM kanye nokulawulwa kwezindleko

Ama-recorder ezwi angahlala ekhiqizwa iminyaka eminingi, ngakho-ke imemori, ama-IC omsindo, izixhumi namadivayisi okushaja kufanele kubuyekezwe ukuze kutholakale ukuthi ayatholakala yini. Ezinye izindlela ezivunyiwe kufanele zirekhodwe kunokuthi zikhethwe ngokungahleliwe ngesikhathi sokuthenga.

Uma ivolumu ephezulu, isu lokuthola ulwazi kanye nokusebenza kahle kokuhlanganisa kungaba yizinto ezibangela izindleko ezinkulu. I-PCB ngokwayo ingaba yingxenye eyodwa kuphela yezindleko ze-PCBA eziphelele.

I-Highleap inikeza ukutholakala kwezingxenye ze-elekthronikhi futhi isekela kokubili izigaba zokukhiqiza i-PCB yokuhlanganiswa enevolumu ephansi kanye nezigaba zokukhiqiza i-PCB yokuhlanganiswa enevolumu ephezulu.

Uhlu oluhlukile oluvunyiwe lunganciphisa ubungozi bokuphakelwa, kodwa ezinye kufanele zifaneleke uma kuqhathaniswa nezidingo zangempela zikagesi nezomshini. Ifektri akufanele ithathe indawo yemakrofoni ehlukile noma i-IC yomsindo ngoba nje iphakheji yayo ifana.

Irekhoda yezwi ingahlala emakethe iminyaka eminingi, ikakhulukazi kwezemfundo, ekubhalweni kwezwi, engxoxweni noma ezicelweni zezikhungo. Ngakho-ke uhlelo lokukhiqiza kufanele lucabangele inkumbulo, i-IC yomsindo kanye nokutholakala kwesixhumi ngaphambi kokuba kukhishwe i-oda elikhulu.

Izinhlelo zokuqopha isikhathi eside kanye nokutholakala kwezingxenye

Lapho umkhiqizo usebenzisa imakrofoni yedijithali, ukuhlolwa kungagxila kakhulu ekuxhumaneni kwesikhombimsebenzisi kanye nokukhipha okuqoshiwe. Lapho kusetshenziswa imakrofoni ye-analog, indlela yokwamukela ingadinga ukumboza indlela yokufaka ye-analog. Ukuhlolwa okulungile kulandela ukwakheka okukhishwe.

Ibinzana elithi “umsindo ophansi” aliyona incazelo eyanele yokukhiqiza. Ukuhlolwa kokukhiqiza kufanele kuhlonze imodi yokurekhoda, isimo sokufaka, ukulungiselelwa kokuzuza, izinga lesampula noma amanye amapharamitha adingekayo ukuze kuphinde kukhiqizwe isilinganiso sokwamukelwa kwekhasimende. Ngaphandle kwalezo zimo, amafektri amabili angabika imiphumela ehlukene evela kumklamo ofanayo.

Ukukhiqizwa kwe-PCB yomsindo kudinga indlela echaziwe yokwamukela

Indlela yokucaphuna i-PCB yerekhoda yezwi yedijithali

Ngezidingo zokukhiqiza ezihlobene, amaqembu e-OEM angabuyekeza futhi ukukhiqizwa kwe-PCB okuvamise kakhulu kanye nokwakhiwa kwe-PCB okuqinile.

Gcina ukwamukelwa komsindo kulinganiswa

Ukuhlolwa kokukhiqiza kufanele kuphindwe ngabaqhubi abahlukene nakuzo zonke izindawo ezahlukene. Ikhasimende kufanele lichaze isimo sokuqopha, umthombo wokufaka noma i-fixture, isilinganiso sokukhipha kanye nomkhawulo wokwamukelwa. Uma kudingeka ukuhlolwa kokulalela okuzimele kuphela, lokho kufanele futhi kushiwo. Ifektri akufanele isungule imininingwane yomsindo engakaze ibe yingxenye yemfuneko yomkhiqizo okhishwe.

Lo mehluko uwusizo uma uqhathanisa abahlinzeki: ifektri eyenza ukuhlolwa kokuhlanganiswa kanye nokuhlolwa komsindo okuchazwe yikhasimende inikeza isevisi yokukhiqiza elinganisekayo, kuyilapho isimangalo mayelana nekhwalithi yokurekhoda ngaphandle kwendlela yokuhlola echazwe kunzima ukuqinisekisa. Izindinganiso zokwamukelwa kufanele zihlale zixhunywe nesidingo somkhiqizo okhishwe.

Uma irekhoda inikezwa abasebenzisi bezikhungo, bezemfundo noma abangochwepheshe, ithimba lokukhiqiza lingadinga nendlela echaziwe yenombolo ye-serial noma indlela yokulandelela i-lot. Lezo zidingo kufanele zishiwo kuphakheji yokukhiqiza kunokuba zengezwe ngokungahleliwe ngemva kokuqala kokukhiqiza.

Thumela i-Gerber/ODB++, i-stack-up, i-BOM, ifayela lokubeka, umdwebo womhlangano, ulwazi lwemakrofoni kanye nesixhumi, idatha yokuhlela, izidingo zokuhlola kanye nobuningi. Sho ukuthi imakrofoni noma ezinye izingxenye zithunyelwe ngamakhasimende.

Kubathengi e-USA, eYurophu, eCanada, eJapane noma e-Australia abathenga eShayina, faka indawo oya kuyo kanye nesheduli. Lokhu kuvumela umhlinzeki ukuthi ahlole ukutholwa kwezingxenye kanye nesikhathi sokukhiqiza kanye nesilinganiso se-PCB.

Ekwakhiweni kokuqala, i-prototyping ye-PCB esheshayo ingasetshenziswa ukuqinisekisa ibhodi ekhishwe ngaphambi kokukhiqiza okuphindaphindiwe.
