Waxaa jira noocyo badan oo PCB ah iyada oo loo marayo daloollada daloolka, iyo apertures kala duwan ayaa lagu dooran karaa iyadoo loo eegayo shuruudaha codsiga iyo shuruudaha naqshadeynta. Kuwa soo socdaa waxay faahfaahin doonaan daloolada PCB-ga caadiga ah ee godadka iyo farqiga u dhexeeya PCB ee godadka iyo godadka.
一, nooca aperture ee PCB ee dalool
1. Aperture Standard (PCB Standard Hole): Sida caadiga ah qaabka PCB-ga, dalool wareeg ah oo leh dalool ka weyn ama la mid ah 0.4mm ayaa loo yaqaan daloolka caadiga ah. Dalooshan waxaa badanaa loo isticmaalaa si loo sugo guddiga PCB-ga iyo isku xirka pin-ka ee qaybaha.
2. Daloolka Micro Hole: Daloolka daloolka Micro waxa loola jeedaa dalool wareeg ah oo dhexroorkiisu ka yar yahay 0.4mm. Iyada oo sii kordheysa miniaturization ee aaladaha elektiroonigga ah, waxaa jira baahi sare oo loogu talagalay naqshadeynta PCB, sidaa darteed apertures micropore ayaa si tartiib tartiib ah caan u noqonaya. Codsiyada loogu talagalay microaperture-ka waxaa ka mid ah aaladaha elektiroonigga ah ee yaryar sida laptops iyo taleefannada gacanta.
3. Daloolka dunta leh (Treaded Hole): godadka dunta leh ayaa lagu shubaa godad, inta badan waxaa loo adeegsadaa in lagu rakibo qaybo leh meelo isku xidhan, sida xidhayaasha ama meelaha kulaylka.
Farqiga u dhexeeya PCB god iyo dalool
PCB-da dalool iyo dalool way ku kala duwan yihiin isticmaalka guddiga PCB-ga, inta badan waxaa jira kala duwanaanshiyaha soo socda:
1. Naqshadeynta PCB: godadka PCB ayaa si ula kac ah loogu hayaa godadka naqshadaynta, waxaana loo habayn doonaa in lagu xidho ugu yaraan laba lakab oo PCB ah. Iyada oo loo marayo godadka waxaa loogu talagalay in lagu xiro lakab ama qayb gaar ah, iyo meesha ay ku yaalaan waxaa lagu go'aamiyaa shuruudaha naqshadeynta.
2, Connection Signal (Xiriirka Signal): PCB dhexda godka waa pin signal ka mid lakabka kale si loo gaaro gudbinta signalada. Godad ayaa inta badan loo isticmaalaa in lagu hagaajiyo looxyada PCB iyo qaybaha iyo bixinta taageero farsamo.
3. Habka wax-soo-saarka: godadka PCB waxa lagu dawayn doona qalab iyo qalab gaar ah inta lagu jiro habka wax-soo-saarka, badiyaa iyadoo la isticmaalayo koronto si loo kordhiyo dhaqdhaqaaqa korantada. Daloolka la maro waa mid fudud, badanaa wuxuu u baahan yahay oo kaliya in lagu farsameeyo dalool booska u dhigma.
4. Taageerada qaabdhismeedka: Jiritaanka godadka PCB waxay kordhin kartaa xasiloonida qaabdhismeedka iyo adayga guddiga PCB, waxayna ciyaaraan door taageero. Inkasta oo daloolku uu sidoo kale kordhin karo heerar gaar ah oo adag, ujeeddadeeda ugu weyn waa inay bixiso hawlo go'an oo isku xiran.
Marka la soo koobo, daloolada PCB ee daloolka waxaa ka mid ah daloolka caadiga ah, microaperture iyo dalool dun leh. Farqiga u dhexeeya PCB ee godadka iyo godadka ayaa inta badan ka muuqda ujeedada naqshadeynta, isku xirka calaamadaha, tignoolajiyada farsamaynta iyo taageerada qaabdhismeedka. Naqshadeynta PCB ee kala duwan iyo shuruudaha isu-ururinta waxaa lagu buuxin karaa iyadoo la dooranayo noocyo kala duwan oo dalool ah iyo iyadoo la adeegsanayo godad ku habboon ama godad-godadka.
