Cabirka iyo cabbirrada looxyada wareegga dhoobada

Boostada blog-ka, waxaan ku sahamin doonaa cabbirada caadiga ah iyo cabbirrada looxyada wareegga dhoobada.

Looxyada wareegga dhoobada ayaa aad iyo aad ugu caan baxay warshadaha elektiroonigga ah iyadoo ay ugu wacan tahay sifooyinkooda sare iyo wax qabadkooda marka la barbar dhigo PCB-yada caadiga ah (Boardyada Wareegga Daabacan). Sidoo kale loo yaqaan PCB-yada dhoobada ah ama substrates dhoobada, looxyadani waxay bixiyaan maaraynta kulaylka oo aad u wanaagsan, xoog farsamo sare leh iyo wax qabad koronto oo heersare ah.

1. Dulmarka looxyada wareegga dhoobada:

Looxyada wareegga dhoobada waxaa laga sameeyaa walxo dhoobo ah sida aluminium oxide (Al2O3) ama silicon nitride (Si3N4) halkii laga isticmaali lahaa walxaha caadiga ah ee FR4 ee loo isticmaalo PCB-yada dhaqameed. Alaabta dhoobada ah waxay leeyihiin kororka kulaylka wanaagsan waxayna si wax ku ool ah u baabi'in karaan kulaylka qaybaha ku rakiban sabuuradda. PCB-yada dhoobada ayaa si weyn loogu isticmaalaa codsiyada u baahan awood sare iyo calaamadaha soo noqnoqda, sida korantada korontada, iftiinka LED, hawada hawada iyo isgaarsiinta.

2. Cabirka iyo cabbirrada looxyada wareegga dhoobada:

Cabirka guddiga wareegga dhoobada iyo cabbiradu way kala duwanaan karaan iyadoo ku xiran codsiyada gaarka ah iyo shuruudaha naqshadeynta. Si kastaba ha ahaatee, waxaa jira qaar ka mid ah cabbirada iyo cabbirada caadiga ah ee sida caadiga ah loo isticmaalo warshadaha. Aynu u daadagno dhinacyadan:

2.1 Dhererka, ballaca iyo dhumucda:
Looxyada wareegga dhoobada waxay ku yimaadaan dherer kala duwan, ballac iyo dhumucyo kala duwan si ay ugu habboonaadaan naqshadaha iyo codsiyada kala duwan. Dhererka caadiga ah wuxuu u dhexeeyaa dhowr milimitir ilaa dhowr boqol oo milimitir, halka ballacyadu ay ku kala duwanaan karaan dhowr milimitir ilaa ku dhawaad ​​250 millimitir. Dhanka dhumucda, inta badan waa 0.25 mm ilaa 1.5 mm. Si kastaba ha ahaatee, cabbiradan waa la habeyn karaa si loo daboolo baahiyaha mashruuc ee gaarka ah.

2.2 Tirada lakabyada:
Tirada lakabyada ee guddiga wareegga dhoobada ayaa go'aaminaya kakanaanta iyo shaqeyntiisa. PCB-yada dhoobada ah waxay yeelan karaan lakabyo badan, oo caadi ahaan u dhexeeya hal ilaa naqshado lix lakab ah. Lakabyo badan ayaa u oggolaanaya isdhexgalka qaybaha dheeraadka ah iyo raadadka, taas oo sahlaysa naqshadaynta wareegga cufan ee sare.

2.3 Cabbirka daloolka:
PCB-yada dhoobada ah waxay taageeraan cabbirrada daloolka kala duwan iyadoo ku xiran shuruudaha codsiga. Godad waxa loo qaybin karaa laba nooc: oo lagu dhejiyay godadka (PTH) iyo kuwa aan dahaadh ahayn ee godadka (NPTH). Cabbirrada godka caadiga ah ee PTH waxay u dhexeeyaan 0.25 mm (10 mils) ilaa 1.0 mm (40 mils), halka cabbirada daloolka NPTH ay noqon karaan kuwo yar sida 0.15 mm (6 mils).

2.4 Raadka iyo ballaca bannaan:
Raadka iyo ballaca bannaan ee looxyada wareegga dhoobada ayaa door muhiim ah ka ciyaara hubinta daacadnimada saxda ah iyo waxqabadka korantada. Balacyada raadraaca caadiga ah waxay u dhexeeyaan 0.10 mm (4 mil) ilaa 0.25 mm (10 mils) waxayna ku kala duwan yihiin iyadoo lagu saleynayo awoodaha qaadista hadda. Sidoo kale, ballaca farqiga u dhexeeya 0.10 mm (4 mil) iyo 0.25 mm (10 mayl).

3. Faa'iidooyinka looxyada wareegga dhoobada:

Waa muhiim in la fahmo cabbirrada caadiga ah iyo cabbirrada looxyada wareegga dhoobada, laakiin sidoo kale waa muhiim in la fahmo faa'iidooyinka ay bixiyaan:

3.1 Maareynta kulaylka:
Dhaqdhaqaaqa kuleylka sare ee alaabta dhoobada ah waxay hubisaa in kulaylka waxtarka leh ee qaybaha awoodda, taas oo kordhinaysa kalsoonida nidaamka guud.

3.2 Awoodda makaanikada:
Looxyada wareegga dhoobada waxay leeyihiin awood farsamo oo aad u wanaagsan, taasoo ka dhigaysa inay aad ugu adkaystaan ​​arrimo dibadeed oo kala duwan sida gariir, shoog iyo xaaladaha deegaanka.

3.3 Waxqabadka korantada:
PCB-yada dhoobada ah waxay leeyihiin luminta dielectric hoose iyo lumis calaamad hoose, taas oo awood u siinaysa hawl-qabadka soo noqnoqda sare iyo hagaajinta daacadnimada calaamadaha.

3.4 Yaraynta iyo naqshadaynta cufnaanta sare:
Sababo la xiriira cabbirkooda yar iyo sifooyinka kulaylka wanaagsan, looxyada wareegga dhoobada ayaa awood u yeelashada yaraynta iyo naqshadaha cufnaanta sare iyadoo la ilaalinayo waxqabadka korantada ee ugu fiican.

4. gabagabadii:

Cabbirrada caadiga ah iyo cabbirrada looxyada wareegga dhoobada way kala duwan yihiin iyadoo ku xiran codsiga iyo shuruudaha naqshadeynta. Dhererkoodu iyo ballacooduba waxay u dhexeeyaan dhawr milimitir ilaa dhawr boqol oo milimitir, dhumucdooduna waxay u dhaxaysaa 0.25 mm ilaa 1.5 mm. Tirada lakabyada, cabbirka daloolka, iyo ballaca raadraaca ayaa door muhiim ah ka ciyaara go'aaminta shaqada iyo waxqabadka PCB-yada dhoobada ah. Fahamka cabbirradan ayaa muhiim u ah naqshadeynta iyo hirgelinta hababka elektaroonigga ah ee hufan ee ka faa'iideysanaya looxyada wareegga dhoobada.
