Habkayaga hal-abuurka leh wuxuu noo ogolaanayaa in aan isku geyno anteenada iyo habka signalka hal xirmo, taas oo meesha ka saaraysa caqabadaha isdhexgalka.Ma aha oo kaliya in tani ay ku badbaadiso waqti iyo dadaal, waxay sidoo kale hubisaa waddooyinka calaamadaha gaaban, yaraynta khasaaraha calaamadaha inta lagu jiro gudbinta iyo habaynta.
Si taxadar leh oo laga sameeyay agab tayo sare leh, looxyadayada PCBA-da waxay ka samaysan yihiin Fr-4, walxo la isku halayn karo oo waara oo loo yaqaano sifooyin koronto oo heersare ah iyo xoog farsamo.Guddidu waxay leedahay lakabyo 6 ah, oo siinaya meel ku filan dhammaan qaybaha lagama maarmaanka ah iyadoo la ilaalinayo shaqeynta ugu fiican.
Looxyadayada PCBA-da ayaa dhumucdiisu tahay 1.2 mm, iyaga oo hubinaya saxnaanta ugu sareysa iyo is dhexgalka aan toos ahayn ee nidaamkaaga amniga.0.102mm/0.1mm raadraaca ugu yar ee dibadda iyo cabbiraadaha ayaa bixiya saxnaanta sare ee waxqabadka sare ee nidaamyada badbaadada.
Godad la qoday oo leh dhexroorka ugu yar ee 0.1 mm ayaa sii wanaajinaya shaqada PCB-ga iyo la jaanqaadka aaladaha amniga ee kala duwan.Waxaan isticmaalnaa teendho iyada oo loo marayo habka si aan uga ilaalino godadka la dalooliyo waxyeellada oo aan u hubinno isku xirnaanta la isku halayn karo ee ka dhexeeya lakabyada kala duwan ee looxa.
Si loo hubiyo nolosha adeegga iyo isku halaynta guddiga PCBA, waxaan u isticmaalnaa daawaynta dusha sare ee nickel immersion gold (ENIG).Daaweynta dusha sare waxay bixisaa waxqabad kiimiko iyo koronto oo heer sare ah, waxay ka hortagtaa daxalka waxayna hubisaa gudbinta calaamadaha ugu fiican.
Ku kalsoonow khibradayada iyo khibradayada warshadaha wax soo saarka elektiroonigga ah.Waxaa naga go'an inaan bixino alaab tayo sare leh oo buuxisa shuruudaha adag ee warshadaha amniga.Maalgashi ku samee guddiyadayada PCBA-da ee badbaadada elegtarooniga ah oo khibrad is dhexgalka aan kala go 'lahayn, naqshadaynta is haysta iyo waxqabadka sare.
