Maxay tahay sababta loo isticmaalo FR-4 si loo sameeyo Tg PCBs sare?

Waa maxay sababta loo isticmaalo FR4 si loo sameeyo Tg PCBs sare?

Codsiyada qaarkood waxay u baahan yihiin PCB-ga inay u adkeystaan ​​heer kulka sare ee 200 ℃ ama ka sareeya.Hawlgalka la isku halayn karo ee codsiyada heerkulka sare, waxaan u baahanahay PCB-yo u go'ay oo la soo saaray iyadoo la adeegsanayo agab waxqabad leh.Balooggaan waxaa loogu talagalay inuu ku baro mid ka mid ah PCB-ga gaarka ah, oo loo yaqaan HIGH-TG.KuwaasPCB-yada sarewaxay u adkeysan kartaa heerkulka kala-guurka dhalooyinka aadka u sarreeya ee PCB-yada iyadoo la siinayo sifooyinka soo socda:

1. xakamaynta impedance oo la hagaajiyay

2. Maamulka kulaylka oo wanaagsan

3. Nuugista qoyaanka oo hooseeya

4. Waxqabad joogto ah

FR4 - Qalabka loo door biday Tg PCB-yada sare

Codsiyada kala duwan ee heerkulka aadka u daran, PCB-yada Tg sare ayaa la soo saaray iyadoo la isticmaalayo substrates FR-4.Fr-4 waa muraayadda ololka dib u celisa ee la xoojiyay walxo epoxy ah oo ku nool wareegyo badan oo lamination, maaraynta PCB adag oo u oggolaanaysa alxan la'aanta rasaasta.Qaybaha caadiga ah ee FR-4 waxaa ka mid ah PTFE saafi ah, PTFE dhoobada ka buuxo, iyo heerkulbeegyada kaarboon-karboonka.Kuwa soo socdaa waa sifooyinka gaarka ah ee substrate-ka FR-4 ee ka dhigaya mid ku habboon PCB-yada dalabka dalabka.

1. Waxqabad koronto oo heersare ah.

2. U adkeysan kara qodista iyo dahaadheynta gaarka ah ee daloolka (PTH) diyaarinta.

3. Dajinta heer sare ah iyada oo loo marayo isku halaynta godka.

4. Kharashku waa yar yahay.

5. Cunsurka kala daadsanaanta deggan (Df) marka la barbar dhigo qalabka kale ee PCB caadiga ah.

6. Iska caabin kiimiko oo heer sare ah

7. Ku haboon naqshadeynta PCB ee u baahan in si adag loo xakameeyo xannibaadda

8. Shockproof, shoogga iyo ololka celiye.

Iyadoo la tixgelinayo waxqabadkeeda gaarka ah ee maaraynta kulaylka, FR-4 High Tg PCBs ayaa si weyn loogu xushay codsiyada xisaabinta, kaydinta iyo meelaha durugsan, qalabka elektiroonigga ah ee macaamiisha, nidaamka isku xirka iyo isgaarsiinta, hawada & Difaaca, caafimaadka, Warshadaha & Qalabka, iyo baabuurta & warshadaha elektiroonigga ah.Warshadaha gaadiidka.

Dooro qalabka saxda ah si aad u gaarto natiijooyinka la rabo

Ka mid ah noocyada walxaha FR-4 ee la heli karo, waxaa muhiim ah in la doorto walxaha saxda ah ee shuruudaha codsiga, maadaama ay go'aaminayso xasilloonida iyo waxqabadka ugu fiican ee qaybta ugu dambeysa.Waxyaabaha ay ka midka yihiin ogolaanshaha dielectric, iskudarka luminta, kulaylka kulaylka, heerkulka kala-guurka, isku xidhka balaadhinta kulaylka (CTE), guryaha korantada, iwm, waa in la tixgeliyaa ka hor inta aanad dooran substrates FR-4 ee codsigaaga.Haddii aad ku wareersan tahay nooca walxaha FR-4 ee aad dooranayso, tixgeli inaad la shaqeyso shirkad PCB ah oo khibrad u leh bixinta Tg PCB-yada sare ee warshadaha kala duwan.RigiFlex Technologies waa mid ka mid ah kuwa caanka ahSoosaarayaasha PCBgudaha suuqa waxayna leeyihiin khibrad gacan-ku-ool ah oo ku saabsan gudbinta Tg PCB-yada sare ee qaabab kala duwan.Codso qiimaha tg PCB sare hadda!
