I-RFQ yokukhiqiza nokuhlanganisa i-PCB ye-radiation detector ephathekayo kufanele itshele ifektri ukuthi yiziphi izindawo zikagesi ezidinga ukwelashwa okukhethekile nokuthi yiziphi izinto ezilethwayo ezibhekene nayo. Ukuthumela amafayela e-Gerber ngaphandle kwemibhalo ye-detector, imikhawulo yokuphatha noma izimo zokuhlola kungase kwanele ukulinganisa ukwenziwa kwe-PCB, kodwa hhayi ngempela ibhodi elihlanganisiwe nelihlolwe ngokuphelele.

Iphakheji yokukhishwa evumela isilinganiso esinengqondo

• Amafayela okukhiqiza: I-Gerber/ODB++, ukuhlanganiswa kwezingqimba, ukudweba ibhodi kanye nezindawo eziphawulwe ngama-voltage aphezulu noma ama-impedance aphezulu, okuhlanganisa noma yiziphi izindlela zokuhlanzeka ezikhethekile noma izikhala.
• Idatha yokuhlanganisa: I-BOM evunyiwe, amafayela okubekwa, imidwebo yokuhlanganisa, izinto ezishintshayo zezingxenye ezibalulekile, imininingwane yesixhumi se-detector kanye nemiyalelo yokulungisa/yokuhlanza evunyelwe.
• Isixhumi esibonakalayo se-detector: I-Tube, inzwa ye-semiconductor, i-scintillation module noma i-integrated-module identification, i-datasheet, izidingo ze-bias kanye nokuthi i-OEM iyawunikeza yini umtshina.
• I-Firmware kanye nezinhlobo: Isithombe sokuhlela, imephu yokucushwa kwehadiwe kuya kusitholi kanye nezidingo zokuphathwa kwedatha ngenombolo yochungechunge noma ngeyunithi ngayinye.
• Umngcele wokuhlola: Isisetshenziswa sikagesi noma i-simulator, imikhawulo yokukhetha kanye neyokuphendula kwe-pulse, amarekhodi okuhlola kanye nomuntu onesibopho sanoma yikuphi ukulinganiswa kwemisebe okuhlukile.
• Ububanzi be-oda: Uhlobo lwesibonelo kanye nobuningi bokukhiqiza obulindelekile, inani lebhodi ngethuluzi ngalinye, izingxenye ezithunyelwe, izidingo zokulethwa kanye nokuthi ukufakwa kwemodyuli yangemva kwe-PCBA kufakiwe yini.

Le mininingwane ivumela i-Highleap ukuthi ihlukanise i-oda lebhodi lokulawula kusuka ku-PCBA ye-detector-front-end ebucayi enokuphathwa okwengeziwe kanye nomsebenzi wokulungisa. Lapho ukuthengwa kwezinto ezivunyiwe, ukwenziwa kanye nenani labantu kudingeka kuhlanganiswe, i-OEM ingacela ukwenziwa kwe-turnkey okuvunyelwene ngakho kanye nobubanzi bokuhlanganiswa kwezingxenye esikhundleni sentengo engachazwanga yensimbi eqediwe.

Ukuze uthole ikhotheshini yokuqala: nikeza amafayela asevele ekhishwe bese ukhomba imininingwane yomtshina noma yokuhlola esalinde ukuvunyelwa. Ububanzi bokukhiqiza bungaxoxwa ngaphandle kokuphatha ukulinganisa okungaqediwe noma ukufaneleka komkhiqizo njengomsebenzi we-PCBA ofakiwe.

imibuzo ejwayelekile ukubuzwa

Ingabe i-PCB yokuhlola ingahlolwa ngokusebenza ngaphandle komthombo wemisebe?

Ngokuvamile, yebo, ngemisebenzi ethile ye-elekthronikhi. Kuye ngesekethe, i-fixture ingahlola ama-power rails, ukubandlulula kwe-detector, ukubala i-logic kanye nokusabela ku-pulse kagesi ejojiwe. Ukuhlolwa okunjalo akubonisi impendulo emisebeni noma ukufundwa kwesilinganiso somthamo esilinganisiwe.

Ingabe kufanele kufakwe i-detector ngesikhathi sokuhlanganiswa kwe-SMT?

Lokho kuncike kudatha ye-detector noma i-module kanye nenqubo evunyiwe. Ezinye izingxenye zingahlanganiswa ngezingxenye ze-elekthronikhi ezivamile; ezinye zidinga ukuphathwa okuvikelekile noma ukufakwa ngemva kokugeleza kabusha nokuhlanzwa. I-OEM kufanele icacise ukuthi i-detector inikezwa ngokwehlukana nokuthi ingafakwa nini.

Kungani i-PCB ingaphumelela ekuhlolweni kodwa isabonisa ukufundwa okungazinzile?

Ukuhlolwa okubonakalayo noma kwe-X-ray akukwazi ukubona yonke inkinga yokuvuza, ukuphazamiseka noma ukucushwa kwe-firmware. Izinsalela eziseduze kokufakwayo kwe-high-impedance, ukuxhumanisa okuvela ku-converter noma iphrofayili yehadiwe engalungile ziyizindlela zokuhlola ezingaba khona. Imbangela yangempela kumele itholakale ngokumelene nesekethe ekhishwe kanye nokusethwa kokuhlolwa okulawulwayo.

Ingabe zonke izitholi zemisebe eziphathwa ngesandla zidinga ama-PCB ane-voltage ephezulu?

Cha. Umklamo we-GM-tube uvame ukuba nesidingo sokukhetha i-high-voltage bias, kodwa ukwakheka kwe-semiconductor kanye ne-scintillation detector kuyahlukahluka. Idivayisi yokuzwa ekhethiwe inquma ukuthi i-high voltage iyadingeka yini nokuthi iyiphi i-circuitry eyengeziwe yomsindo ophansi noma i-module interface edingekayo.

Yini okufanele iHighleap icelwe ukuba icaphune ngokwehlukana?

Khomba noma yimaphi amamojula okuthola athunyelwe, izinto zokuhlola ezisebenzayo ezenziwe ngokwezifiso, ukuhlanza noma ukuphatha okukhethekile, ukufakwa kwamamojula ngemva kokuhlanganiswa, kanye nokulinganisa noma isitifiketi ngaphandle kokukhiqiza okuvamile kwe-PCB/PCBA. Lowo mehluko wenza izingcaphuno kanye nemithwalo yemfanelo yokwamukela icace kakhudlwana.

Izidingo zokukhiqizwa kwe-PCB, ukuhlanganiswa kanye nokuhlolwa ziqinisekiswa ngokumelene nomklamo okhishwe, imiyalelo yabaphakeli bezingxenye kanye nanoma yiziphi izidingo zokufaneleka komkhiqizo wokugcina ezisebenzayo.
