PCB-ga caadiga ah ee PCB Countersink ee laba-geesoodka ah | YMSPCB

Hordhac Wareegtada Guddiga Wareegga

A wareegsan oo mechanically supports and electrically connects electrical or electronic components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it.PCBs can be single-sided (one copper layer), double-sided (two copper layers on both sides of one substrate layer), or multi-layer (outer and inner layers of copper, alternating with layers of substrate). Multi-layer PCBs allow for much higher component density, because circuit traces on the inner layers would otherwise take up surface space between components. The rise in popularity of multilayer PCBs with more than two, and especially with more than four, copper planes was concurrent with the adoption of surface mount technology.

Looxyada wareegyada laba-geesoodka ah ayaa xoogaa ka dhib badan PCB-ga hal dhinac ah. Looxyadani waxay ka kooban yihiin hal lakab oo ah substrate-ka hoose. Si kastaba ha ahaatee, waxay ka kooban yihiin lakabyo conductive ah dhinac kasta. Waxay u isticmaalaan naxaas sida walxo dhaq-dhaqaaq ah. Aan sii muquunno gudaha PCB-ga laba-geesoodka ah si aan wax badan u barano!

Qaab-dhismeedka iyo Agabka PCB-ga laba-geesoodka ah

Walxaha PCB-ga laba-geesoodka ah way kala duwanaan karaan iyadoo lagu saleynayo nooca mashruuca. Si kastaba ha ahaatee, walxaha asaasiga ahi waxay ku dhow yihiin isku mid dhammaan looxyada wareegga. Si kastaba ha ahaatee, qaab dhismeedka PCB wuu ku kala duwan yahay nooca ilaa nooca.

Substrate: waa shayga ugu muhiimsan ee laga sameeyay fiberglass. Waxaad u qaadan kartaa sidii qalfoofka PCB-ga.

Lakabka Copper: Waxay noqon kartaa mid bireed ama dahaar buuxa oo naxaas ah. Taasi waa sababta ay ku xiran tahay nooca guddiga. Natiijada kama dambaysta ahi waa isku mid haddii aad isticmaashid dahaarka bireed ama naxaasta. Looxyada wareegga laba-geesoodka ah waxay ka kooban yihiin lakab naxaas ah oo labada dhinac ah.

Maaskarada Alxan: Waa lakabka difaaca ee polymer. Sidaa darteed, waxay ka hortagtaa naxaasta wareegga gaaban. Waxaad u tixgelin kartaa sida maqaarka guddiga wareegga. Alxanka PCB-ga laba-geesoodka ah waa tallaabo aad muhiim u ah adkeysiga.

Shaashadda xariirta: waa qaybta ugu dambeysa ee muraayadda xariirta. Inkastoo aysan wax door ah ku lahayn shaqeynta guddiga wareegga. Soo-saareyaashu waxay u isticmaalaan inay muujiyaan nambarada qaybta. Nambarada qaybuhu aad bay muhiim ugu yihiin ujeedooyinka tijaabada. Intaa waxaa dheer, waxaad daabacan kartaa calaamadaha shirkaddaada ama macluumaadka kale oo qaab qoraal ah.

Faa'iidooyinka iyo Khasaaraha ay leeyihiin Guddiyada Wareegga ee Laba-geesoodka ah

Waa kuwan qaar ka mid ah faa'iidooyinka iyo khasaarooyinka looxyada wareegyada daabacan ee laba-geesoodka ah:

Faa'iidooyinka Guddiyada Wareegga ee Laba-dhinac ah

Tayada Sare: Qorshaynta iyo naqshadaynta PCB-gan waxay u baahan yihiin shaqo fiican. Taas oo keentay loox-wareeg tayo sare leh.

Meel bannaan oo ku filan Qaybaha: Waxay haysaa boos badan oo qaybaha ah. Sababtoo ah labada dhinac ee lakabka ayaa ah kuwa qabanaya.

Ikhtiyaar Naqshad Badan: Waxay leedahay lakabyo wax-qabad oo labada dhinac ah. Waxaad ku dhejin kartaa qaybaha elektarooniga ah ee kala duwan labada dhinacba. Markaa waxaad haysataa doorashooyin badan oo naqshadeed.

Dajinta iyo Qulqulka Hadda: Markaad u isticmaalayso lakab hoose, waxaad u isticmaali kartaa quusinta iyo soo saarida hadda.

Isticmaalka: waxtarkeeda awgeed, waxaad u isticmaali kartaa codsiyo badan.

Faa'iido darrada looxyada wareeg ee laba-geesoodka ah

Kharashka Sare: Ka dhigista labada dhinacba kuwa dhaq-dhaqaaqa, waxay ku timaadaa kharash yar oo sarreeya.

Naqshadeeye Xirfad leh ayaa Loo Baahan Yahay: Waxa ku lug leh hab-soo-saar PCB-ga samayntiisa xoogaa adag oo laba-geesood ah. Sidaa darteed, waxaad u baahan tahay injineero aad u yaqaana wax soo saarkeeda.

Waqtiga Wax-soo-saarka: Waqtiga wax-soo-saarku wuu ka badan yahay hal dhinac oo PCB ah sababtoo ah kakanaanta.

Codsiga looxyada wareegyada laba-geesoodka ah

Noocan ah guddiga wareegga wuxuu kordhiyaa cufnaanta wareegga. Iyagu sidoo kale aad bay u dabacsan yihiin. Ku dhawaad ​​dhammaan soosaarayaasha PCB-ga laba-geesoodka ah waxay ku isticmaalaan qalabyo badan oo elegtarooniga ah. Hoos waxaa ku qoran qaar ka mid ah kiisaska isticmaalka cajiibka ah ee looxyada wareegyada laba-geesoodka ah:

HVAC iyo nalalka LED

Nidaamka xakamaynta gaadiidka

Boodhadhka baabuurta

Xakamaynta wareejinta iyo beddelka Awoodda
