How to calculate the sampling cycle of small batch PCBA?

In the domestic PCBA is a general term for PCB welding, including: PCB circuit board,smt patch and component welding three parts. Whether it is PCB proofing or small batch PCBA proofing or PCB mass production, it is very important to ensure customer delivery. As far as the proofing cycle is concerned, the editor will analyze it today, hoping to give everyone a simple understanding of the PCBA proofing cycle.
Small batch PCBA proofing

PCB circuit board: The customer needs to provide board-making information and board-making instructions. Jedduobang has its own PCB online ordering system. Customers can fill in relevant parameters and upload relevant board-making files according to their own board-making needs, and the system will automatically give Quotation and delivery time, of course, some special requirements should be clearly noted to avoid unnecessary problems in advance.

Smt patch: This is mainly an accounting of processing fees. Smt is generally calculated based on one piece or one point. What needs to be figured out is that maybe one point is one point, or one foot is one point, and one piece has at least one point. 2 feet, the price of the points calculated in this way is different. For example, if you calculate one by one point, the single point price will be higher than the unit price of one foot and one point. So don't judge the point when the unit price is high. The points are calculated on a point by point basis or a point by foot.

Component welding: components have conventional resistance-capacitance and special components. At present, the price of conventional components is transparent in the market, and it is easy to evaluate the price; but for some special components, such as BGA/IC, the price evaluation is a little more troublesome. Many special components involve international embargoes, strict approval procedures, long passage time and unstable prices, so the quotation cycle is generally delayed for a few days.

Summarizing the above analysis: the quotation time for small batch PCBA proofing can be done in a few hours at the fastest, and it may take a few days at the slowest. As a PCB manufacturer, in the case of a large number of orders, it must be the one who reports first, which also has a certain impact on the small batch PCBA proofing cycle. Of course, if it is just a single multi-pcb proofing or smt patch proofing, the cycle is still relatively fast.
