Aunque afectará la eficiencia de producción, puede garantizar mejor la calidad.
Before assembly, 100% of our electrical boards must pass a rigorous 12-hour temperature stress test—enduring -25°C, 45°C, and room temperature for 4 hours each. Following this, every board undergoes a strict final performance check to guarantee maximum stability and reliability.
En términos de operaciones de soldadura, hemos invitado a un ingeniero que ha estado involucrado en soldadura en BMW en Alemania durante 25 años para supervisar el trabajo y, como resultado, la tasa de fallas por fugas de nuestros productos es menor a 0.1%.
Our automated production line ensures precision and care at every step. Casings are safely transported by tool trolleys, and post-assembly units are sent via conveyor belts for cooling tests. To prevent handling scratches, we use vacuum suction lifters during packaging. Once fully packed, all units are automatically conveyed to the warehouse.
We simulate diverse environmental conditions during testing to ensure optimal real-world performance. This comprehensive approach allows us to continuously refine and tailor our products to meet the specific demands of various global markets and distribution channels.
We always believe that only strictly tested products can meet our customers’ expectations and win us a good reputation in the market. Our products have to go through several critical tests, the first cooling test, the second HI-POT test, the third product configuration double-check, the fourth performance test, and the fifth high voltage test.
La tarjeta de seguimiento de inspección de calidad es una medida para controlar estrictamente la calidad de nuestros productos. Registra detalladamente todo el proceso del producto, desde la compra de la materia prima, la producción y el procesamiento, las pruebas del producto terminado hasta su envío.
Basado en los principios de sinceridad, cooperación e innovación.
