Casos recientes de la industria han demostrado que algunos fabricantes experimentaron fallas funcionales en lotes completos de PCBA debido a la falta de un zumbador. (Referencia SPK) during the SMT process. As a leading one-stop PCBA solutions provider, Fully Hong has conducted an in-depth investigation into such failures and implemented robust mistake-proofing systems that eliminate these issues at the source.
1. Causa principal: Why Was the Buzzer Not Mounted?
The Fully Hong engineering team reverse-engineered the failure and traced it to a series of breakdowns across three critical stages: design, production, and quality control.
✅ Key Findings:
-
Design Deficiency:
The PCB pad supported both SMT and DIP processes, but the preferred assembly method wasn’t clearly specified. -
Production Misinterpretation:
The English BOM description differed from the Chinese production interface, causing SMT operators to incorrectly assume the component was to be surface-mounted. -
Quality Control Oversight:
IPQC failed to verify the assembly route. The DIP workstation assumed the buzzer had already been mounted via SMT.
2. Fully Hong’s Preventive Mistake-Proofing Mechanisms
At Fully Hong, we’ve developed a multi-layered quality assurance framework that ensures zero component omission—especially for hybrid-process parts such as buzzers.
Triple-Layer Mistake-Proofing System
1. Smart Design Review System
-
Automatically detects components that support both SMT and DIP
-
Enforces mandatory designation of preferred process (P.EJ., “DIP ONLY”)
-
Gerber files include auto-generated process-layer warning markers
2. Production Execution Safeguards
-
Multilingual BOM auto-conversion system (supports 12 languages)
-
MES system validates process routing in real-time
-
SMT machines automatically ignore non-SMT component positions
3. Full-Process Quality Gating
-
First Article Inspection follows “Triple Verification” (Proseperar / Drawing / Physical Sample)
-
AOI program trained to detect hybrid-process components
-
Handover checkpoints require dual-signature confirmation between stations
