3. VEIKONG Manufacturing Enviroment
R&D test: test the hardware and software performance, to make the design more optimization, makes sure the products have excellent
performance before production;
Board test: test the performance of every board in our products, to reduce product defective rate;
IQC: take strict quality inspection for every income components, to ensure every income components are qualified.
Aging test: make the solar pump VFDs at run status, put them in the aging test house at 50°C for 48 hours, to remove every unqualified products.
Load test: the last and the most important test, add different load to the solar pump VFDs, test their input and output value, to check their
working performance. unqualified products will be removed from the team.
By applying such strict testing process, VEIKONG ensures every outgoing solar pump VFD has excellent quality.
