Reliability Test Service
Reliability Testing Services
The automotive industry, closely tied to life and property, cannot tolerate product design flaws or reliability defects, as these can lead to massive compensation claims for automakers. The automotive sector must transcend the mindset of consumer electronics and adhere to uncompromising quality and reliability standards. Automakers often require a 3 to 5-year verification period for new product introductions and may demand up to 20 years of after-sales maintenance support. In automotive electronics design, "Design for Reliability" must replace the "Time to Market" mindset typical of consumer products.
Professional Service and Commitment
Wellysun has achieved IATF 16949 certification and passed numerous automotive manufacturer audits, ensuring the delivery of stable, automotive-grade electronic module products. From Wellysun's perspective, meeting automakers' quality control and reliability requirements in product design is the first step. However, integrating into the automotive supply chain involves more than design; it includes product development, manufacturing, installation, and service, all governed by the IATF 16949:2016 automotive quality management system. This system applies across the entire automotive OEM market supply chain, covering manufacturing, production part suppliers, or providers of services such as welding, electroplating, and painting. The process can be summarized into three key aspects: system, process, and product specification.
Step-by-Step Verification
When automakers develop a product and its features, Step 1 defines system functionality, Step 2 defines subsystem functionality, Step 3 involves selecting the electronic control units (ECUs), and Step 4 focuses on the semiconductor components required. The specifications proceed from left to right, top to bottom. However, during verification, the process reverses, proceeding step-by-step from bottom to top. Ensuring quality from the source is the key to achieving high reliability.
Following the V-Curve
Failure to follow the V-curve can make it difficult to determine whether a product issue stems from prior product problems, manufacturing issues, or design flaws. Standards such as IPC, MIL-STD, and IEC are commonly cited for various environments and conditions. Popular automotive electronic standards include AEC-Q100/101/102/104/200 and ISO 16750, which are widely adopted. Below is a summary of key steps from automotive components to system modules.
STEP1
Component Level–- Active components (ICs) meet AEC-Q100 standards
- Discrete components meet AEC-Q101 standards
- LEDs meet AEC-Q102 standards
- Multi-Chip Modules (MCMs) meet AEC-Q104 standards
- Passive components meet AEC-Q200 standards
STEP2
PCB Level–
- Printed Circuit Boards (PCBs) verified under IPC-6012DA
STEP3,4
Board Level–
- Consider solder joint reliability after component mounting (Board Level Reliability, BLR)
- Verify PCBA process quality
STEP5
System Level–
- From system modules to Tier 1/brand automakers' standards
