2. Understand product service life

When enterprises buy products, they all hope that the longer the service life of the products, the better. In this case, it is necessary to understand the service life of the products first. Here we need to pay attention to one thing, that is, do not unilaterally listen to the manufacturer's introduction, but to carry out market research on the product, only the market research results can be authentic. Because no one says their products are bad.

3. Understand the reputation of merchants

Enterprises in the procurement of products, are generally large-scale procurement, so not every product to test whether qualified. Below this kind of circumstance, must cooperate with manufacturer of big brand, such ability can avoid manufacturer shoddy.

4. Compare market prices

When the product quality, service life, business reputation after the determination, you can consider the price, this time which one manufacturer price is cheaper to choose which one.

For enterprises, the cheaper the power module price is, the better, because the price is cheap, the enterprise profit space will be large, but the premise of cheap price is not poor product quality, if the product quality is poor, the price is no use, the enterprise will use this product, but will lead to their reputation worse, more than the gain.
