I'm going to place a large order, but I need to test your quality first. Is that possible?
A: Absolutely. You can place a prototype order first and adopt the following two options to check the quality and then inform us whether if you want to place order for the mass production.
Option 1: We can send board images for your basic check and inspection. Once confirmed, you may order products in large quantity and we will ship all circuit boards to you at one time.
Option 2: We can ship some boards to you for your comprehensive inspection. Once confirmed, you may order the rest boards.
