Firstly, Yingstar have good cooperation relationships with the world famous electronic components suppliers or their first class agents, like Microchip, Atmel, TI, ST, NXP, TOSHIBA, Fairchild, Linear, Murata,Samsung, Ublox, Quectel, Simcom, Telit and Raytac., etc. That means we can directly apply from them for good price and technical support. And if customers have batch order quantities and can accept a little longer lead time, Yingstar can apply very good prices from the original parts suppliers.
For small quantity orders or prototypes, in order to test the product functionality or test the market, customers usually requires very short lead time, but the quantity might be too less for original manufacturers. But please do not worry, we also have good partnerships with Digikey, Mouser, Element14, Arrow and LCSC, so as to provide customers short lead time parts.
Secondly, Yingstar has a team of engineers whom are very familiar with China local made electronic components. For the resistors, capacitors, connectors, headers, speakers, buzzers, diodes, triodes, modules, batteries, switches, cables..., Chinese manufacturers also can make them with very good quality and very cheaper price. Once get customers’ BOM list, our engineers will compare the original parts with China local parts to see if it’s replaceable. If it’s replaceable, we will send the datasheet to customer for checking and approving. In this way, the parts cost can be greatly reduced.
