CT Sinyal Şartlandırıcı Tasarımı

Thought for 45 sec

Ekran goruntusune gore genel yerlesim dogru yonde (sol: J1/R_BURDEN, sag: J2), ama kablolama (airwire) uzunluklari ve izolasyon bariyeri etrafinda “blok” sirasi karismis. Asagidaki tasimalar, hem daha temiz routing hem de izolasyon kurallarina uyum icin en hizli iyilestirme olur:

1) Izolasyon bariyerini ortala ve yan yana yap

U3 ile U_DCDC’yi kartin tam ortasinda, birbirine cok yakin ve dikey slotu kopruleyecek sekilde yan yana konumlandirin.
Hedef: U3’nin sol pinleri “primary”, sag pinleri “secondary” tarafinda kalsin; U_DCDC icin de aynisi.
Su an ikisi ortada ama aralari ve baglantilari daginik; ortadaki airwire “yelpazesi” bu yuzden buyuyor.

2) Primary zinciri solda tek blok haline getir

Sol tarafta sira su olmali (soldan saga):

Giris: J1 -> yuk: R_BURDEN (zaten yakin, guzel)
Dogrultucu blogu: U1 + etrafinda D1, D2, R1, R2, R3, R4
- Su an D1/R1/R3/R4 biraz “ortaya” kacmis gorunuyor; hepsini U1’in hemen yanina toplayin.
Filtre blogu: R5 + C1 + R6 + C2
- Su an C1 ortanin ustunde “yalniz” kalmis; R5 ve R6 ile ayni bloga alin (primary tarafta, U2’ye dogru akan bir hat).
LED surucu: U2 + R7 + R8
- Bu ucunu, U3’nin primary tarafina en yakin olacak sekilde yerlestirin (R7/R8 airwire kisalir).

3) Secondary zinciri sagda tek blok haline getir

U4’u U3’nin secondary pinlerine yakin koyun; R9 da U3 ile U4 arasina gelsin.
Kazanc/ayar blogu: Rg, Rf, RV1 U4’un yaninda, birbirine yakin olmali.
- Su an RV1 fena degil ama Rf/Rg ile “ucgen” daha sikistirilabilir.
Cikis/koruma: Rs, D3, C7 tam J2’nin soluna alin (en sagda J2 olsun).

4) Dekuplajlari dogru IC’lere yapistir

Bu, routing’i dramatik kisaltir:

C10 U1’e yakin
C11 U2’ye yakin
C3 + C4 U_DCDC giris pinlerine yakin (primary taraf)
C5 + C6 U_DCDC cikis pinlerine yakin (secondary taraf)
C8 + C9 U4’e yakin

5) Test point’leri ilgili blogun yanina koy

TP1 R_BURDEN cikisinda (primary, yuksek akim bolgesi)
TP2 D1/D2 katot birlesiminde (dogrultucu cikisi)
TP3 C2 dugumunde (filtre cikisi)
TP4 U4 TIA cikisinda (secondary)
TP5 J2 oncesinde (ADC_OUT)

Isterseniz bir sonraki ekran goruntusunde bana sadece su 2 seyi gosterin:

Izolasyon slotunu cizdiniz mi (X~60 mm’de)?
U3 ve U_DCDC slotu kopruleyecek sekilde ortalandi mi?

Ondan sonra yerlesimin “son dokunus”unu (hangi parca 2-5 mm kaydirilmali / hangi yone cevrilmeli) daha nokta atisi soylerim.
