A cikin taron PCBA, zaɓin abu yana da mahimmanci ga aikin jirgi da aminci.Anan akwai wasu la'akari don solder, PCB da zaɓin kayan marufi:
Abubuwan zaɓin solder
1. Lead Free Solder vs Leaded Solder
Solder mara gubar yana da daraja don kyawun muhallinsa, amma yana da mahimmanci a lura cewa yana da yanayin zafi mai girma.Leed solder yana aiki a ƙananan zafin jiki, amma akwai haɗarin muhalli da lafiya.2.
2. Abun narkewa
Tabbatar cewa wurin narkewa na zaɓin solder ya dace da buƙatun zafin jiki na tsarin taro kuma ba zai haifar da lalacewar abubuwan da ke da zafi ba.
3. Ruwan ruwa
Tabbatar cewa mai siyar yana da ruwa mai kyau don tabbatar da isassun jikewa da haɗin haɗin haɗin gwanon.
4. Juriya mai zafi
Don aikace-aikacen zafin jiki mai girma, zaɓi mai siyar tare da kyakkyawan juriyar zafi don tabbatar da kwanciyar hankali na haɗin gwiwa.
Abubuwan zaɓin zaɓi na kayan PCB
1. Substrate abu
Zaɓi kayan da ya dace, kamar FR-4 (gilashin fiber ƙarfafa resin epoxy) ko wasu manyan mitoci, dangane da buƙatun aikace-aikace da buƙatun mitar.
2. Yawan Layer
Ƙayyade adadin yadudduka da ake buƙata don PCB don saduwa da buƙatun jigilar sigina, ƙasa da jirage masu ƙarfi.
3. Halayen impedance
Fahimtar ƙayyadaddun ƙayyadaddun ƙayyadaddun kayan da aka zaɓa don tabbatar da amincin sigina da daidaita buƙatun biyu na banbance-banbance.
4. Thermal Conductivity
Don aikace-aikacen da ke buƙatar zubar da zafi, zaɓi wani abu mai mahimmanci tare da kyakkyawan yanayin zafi don taimakawa wajen watsar da zafi.
Abubuwan zaɓen kayan kunshin
1. Nau'in kunshin
Zaɓi nau'in fakitin da ya dace, kamar SMD, BGA, QFN, da sauransu, dangane da nau'in kayan aiki da buƙatun aikace-aikace.
2. Abun rufewa
Tabbatar cewa zaɓaɓɓen kayan rufewa ya dace da buƙatun aikin lantarki da na inji.Yi la'akari da abubuwa kamar kewayon zafin jiki, juriya na zafi, ƙarfin inji, da sauransu.
3. Kunshin thermal yi
Don abubuwan da ke buƙatar zubar da zafi, zaɓi kayan kunshin tare da kyakkyawan aikin zafi, ko la'akari da ƙara ma'aunin zafi.
4. Girman kunshin da tazarar fil
Tabbatar cewa girman da tazarar fil na fakitin da aka zaɓa sun dace da shimfidar PCB da shimfidar ɓangaren.
5. Kariyar muhalli da dorewa
Yi la'akari da zabar kayan da ke da alaƙa da muhalli waɗanda suka dace da ƙa'idodi da ƙa'idodi masu dacewa.
Lokacin zabar waɗannan kayan, yana da mahimmanci a yi aiki tare da masana'antun PCBA da masu siyarwa don tabbatar da cewa zaɓin kayan ya cika buƙatun takamaiman aikace-aikacen.Hakanan, fahimtar fa'idodi, rashin amfani da halaye na kayan daban-daban, gami da dacewarsu don aikace-aikace daban-daban, shine mabuɗin yin zaɓin da aka sani.Yin la'akari da ƙarin yanayin solder, PCB da kayan marufi yana tabbatar da aiki da amincin PCBA.
