When you partner with <\/span>S<\/span>e<\/span>e<\/span>e<\/span>d<\/span> for an <\/span>ODM<\/span><\/b><\/a> project, you\u2019re looking for a smooth, high-quality journey from concept to mass production. That journey isn’t just about design and assembly; it\u2019s secured by rigorous testing at every major milestone. We don’t just build your product\u2014we relentlessly validate it to ensure it\u2019s robust, reliable, and ready for the global market.<\/span><\/p>\n

Let’s break down the three core phases of testing we use to guarantee your product’s success.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The <\/span>EVT phase is all about the <\/span>initial hardware and software functionality<\/span><\/b>. Think of this as the “Does it actually work?” stage. We take the core concept and build a preliminary prototype to ensure the fundamental design is sound.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Test type<\/th>Introduction<\/th>\n<\/tr>\n<\/thead>\n
Electrical Performance Testing<\/td>This checks if the core electronic components (like the PCB, power supply, and main chip) are running within their designed electrical limits (voltage, current, impedance, etc.). We're looking for any initial electrical bugs.<\/td>\n<\/tr>\n
Functional Testing<\/td>This verifies that the product performs its intended functions according to your specifications. For example, if it's an IoT sensor, we check if it can power on, connect to a network, and read\/transmit data correctly.<\/td>\n<\/tr>\n
Certification Pre-Scan<\/td>We perform preliminary checks for electromagnetic interference (EMI) and electromagnetic compatibility (EMC) to catch potential compliance issues early. Finding these problems now saves major headaches later!<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Once we know the basic concept works (EVT approved!), we move to DVT. This stage is focused on <\/span>design robustness, reliability, and preparing for mass-scale manufacturing<\/span><\/b>. We use near-final hardware and firmware.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Test type<\/th>Introduction<\/th>\n<\/tr>\n<\/thead>\n
Reliability Testing<\/td>This is where we stress-test the product's endurance. It includes environmental stress tests like exposure to extreme temperatures, humidity, and vibration to see how the product holds up under real-world conditions.<\/td>\n<\/tr>\n
EMI\/EMC Testing (Rigorous)<\/td>A comprehensive re-run of the electromagnetic tests. This ensures the product won't interfere with other devices and is compliant with international regulatory standards (a critical step for global market access).<\/td>\n<\/tr>\n
System Performance Testing<\/td>This test measures the product\u2019s speed, efficiency, and overall performance under typical and maximum load conditions. For example, how fast does the processor run? How long does the battery last?<\/td>\n<\/tr>\n
DFM\/DFT Review (Design for Manufacturing\/Test)<\/td>Although technically a review, it ensures the design is easy to assemble efficiently and that effective testing points are built into the production process itself.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

PVT is the final checkpoint before we hit the “GO” button on mass production.

Process Validation<\/td>We run a small-scale pilot production to ensure the assembly line, tooling, and manufacturing processes are stable, efficient, and consistently producing high-quality units at the required speed.<\/td>\n<\/tr>\n
Final Quality Control (QC)<\/td>This involves comprehensive inspections and in-line tests during the pilot run to catch any defects introduced by the assembly process, ensuring high yield rates.<\/td>\n<\/tr>\n
Packaging & Drop Testing<\/td>We test the product's packaging design by simulating rough handling during shipping (like drop tests) to ensure the final product reaches your customers safely, without damage.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
