Fixing Copper Short Issue

Thought for 45 sec

Evet - bunu biraz daha daralttım.

Sonuç

Bu hata doğrudan U3 pad’i ile J4 pad’inin üst üste gelmesinden çok, +3V3_MAIN izinin J4 pad 26’ya değmesinden kaynaklanıyor gibi görünüyor.

Neden böyle diyorum

J4 pad 26 footprint içinde mevcut.
U3 üzerindeki VDD pad’leri: 17, 30, 39, 52, 62, 72, 84, 108, 121, 131, 144
JSON’da +3V3_MAIN için Top layer’da uzun bir iz zinciri var.
Bu yüzden review metnindeki Des: U3:VDD büyük olasılıkla iz o VDD ağından geliyor anlamına geliyor; yani çarpışan obje çoğunlukla iz/fanout, doğrudan U3 pad’i değil.

En olası nokta

Önce şuraya bak:

J4 pad 26
Onun yakınından geçen +3V3_MAIN Top trace
Özellikle U3 tarafındaki VDD fanout çıkışları

Pratik düzeltme

Sadece Top katmanı açık bırak.
Review satırından hataya tıklayıp zoom yap.
J4 26 pad’ine değen:
- ince bir iz,
- kısa fanout parçası,
- veya küçük bakır artığı arayın.
Bulunca:
- o kısa iz parçasını silip yeniden kaçır,
- ya da şekli küçültüp pad 26’dan ayır.

En iyi çalışma varsayımı

İlk inceleyeceğin yer:

J4 26
U3 tarafında VDD 62 / 72 / 84 yönünden gelen +3V3_MAIN izi

İstersen bir sonraki adımda sana “J4 pad 26 çevresinde hangi Top trace segmentleri şüpheli” diye daha net bir kısa liste çıkarayım.

Amacın, ChargeGuard Gateway PCB yerleşimini DRC’ye uygun hale getirmek için bir plan oluşturmak.

Plan hazır ve çalıştırılmaya uygun.
Ana adımlar:
1. DRC hatalarını sınıflandırıp önceliklendirmek
2. Önce VIN_PROTECTED, VIN_FILTERED, +5V_MAIN, +3V3_MAIN bölgelerini temizlemek
3. Kalan overlap, floating copper ve airwire’ları kapatmak
4. Her turdan sonra DRC’yi tekrar kontrol ederek sıfıra inmek

Description

ChargeGuard Gateway - PCB layout review status: schematic power tree review is clean; remaining work is PCB-layout-only cleanup. Current DRC inventory: 136 Overlapping Copper, 56 Floating Copper, 88 Airwires, 0 Missing Footprints, 0 Invalid Layer, 0 Important Overrides. Priority 1: protected input and power-path regions around VIN_PROTECTED, VIN_FILTERED, +5V_MAIN, +3V3_MAIN because these can block reliable routing and copper pours. Manual PCB editor tasks: remove/reshape overlapping copper, reconnect broken traces or redraw routes causing airwires, delete stranded copper islands, inspect ambiguous pad-to-trace shorts around power devices and connectors. Agent-preparable tasks: maintain issue inventory, classify nets and priorities, preserve stackup/documentation, define DRC recheck loop, and guide Auto-Layout sequencing after manual copper cleanup. Recheck loop: fix one issue class or one critical region at a time, rerun DRC, confirm counts decrease, then move to next batch until airwires/floating copper/overlaps are zero. Completion checklist: 1) clear power-path overlaps, 2) remove floating copper islands, 3) close all airwires, 4) rerun DRC after each batch, 5) confirm clean layout before manufacturing export.
