[Case Study] Circuit Board Inspection for Consumer Products
Please utilize Takaya's flying probe tester for circuit board inspection for consumer products.
In the mass production process of circuit boards for consumer products, conducting constant inspections of chip components and verifying the mounter program before assembly helps prevent lot outs and defective products from being released, achieving both efficiency in the manufacturing process and improved quality. 【Implementation Results】 - In the process of switching models for mass-produced high-density assembly boards, program verification of the mounter and constant inspections of chip components were conducted. - Efficient manufacturing processes were realized through short-duration and high-precision inspections. 【Challenges Faced by Customers】 Component Set Mistakes: There is a risk of component set mistakes during the assembly process or the installation of non-specified components. Particularly in mass production, if mistakes are discovered late, it can lead to a large number of lot outs. Program Mistakes: Due to errors in the mounter's program settings, there is a possibility that incorrect components are installed on the circuit board. If a setting mistake is discovered in a later process, the costs for rework or disposal increase. Limitations of Visual Inspection: Manual and visual checks depend on the skill and fatigue of the operator, making it easy for inspection omissions and false detections to occur.
basic information
**Benefits of Introducing Flying Probe Testers** Efficient Inspection through Simple Temporary Mounting: By temporarily mounting chip components on a bare board with double-sided tape and making contact with the electrodes, electrical characteristic constant inspections can be conducted. This temporary mounting method allows for inspections without placing direct burdens on the assembly machines or the circuit boards. Elimination of Human Errors: Accurate and quick inspections are achieved through machines, without relying on manual labor or visual checks. Inspections conducted before the assembly stage reduce the risk of defects across the entire lot. Enhanced Program Verification: Verification of the consistency between the mounter's program and the components helps prevent implementation program errors. This suppresses the occurrence of defects due to program errors during model switching. Improved Stability in Mass Production Processes: Constant inspections of components ensure stability in the assembly process. This prevents the outflow of defective products due to initial setup errors or changes in the process, thereby improving production yield.

**Effects of Implementation** Prevention of Defective Product Leakage: By verifying components before the assembly stage, we prevent defective parts and incorrectly mounted items from flowing onto the production line. This stabilizes the quality of high-density mounted circuit boards. High-Precision Inspection in a Short Time: By adopting a provisional mounting method, we conduct constant inspections of chip components quickly and accurately. This establishes an efficient production flow through pre-assembly inspections. Improvement of Mass Production Reliability: Early detection of setup errors in assembly machines and supply errors of components. Minimizing troubles during model changes enhances manufacturing reliability. **Application Examples** Home Appliance Circuit Boards: Verifying constants such as capacitors and resistors to eliminate defective parts. Mobile Device Circuit Boards: Checking for placement errors and constants of chip components on high-density mounted circuit boards. Small Electronic Device Circuit Boards: Preventing incorrect mounting due to setup errors in the mounter.
