The lead time for PCBA sampling is the result of a combination of multiple factors. From PCB production to component procurement, to SMT/DIP processing and testing, every step may have an impact on the overall processing cycle.
Firstly, we need to understand the basic lead time for PCB sampling. According to industry practices, the lead time for sampling PCB boards with different layers may vary
Double sided board: The sample delivery time is usually 5-7 days, and the mass production delivery time is around 12 days.
4-6 layer board: Sampling takes 10-15 days, and batch production delivery takes 25-30 days.
8-layer board: The sampling time is usually 20-25 days, and the delivery time for mass production is 35-40 days.
It is worth noting that these times are for reference only, and the actual production time may vary depending on the specific situation and order volume of the factory.
In the PCBA sampling process, the procurement time of components is also an important factor affecting delivery time. For common components, most processing plants have a certain inventory to quickly meet production needs. But for some special components or original components, the procurement cycle may be longer, sometimes even more than a month. Therefore, when determining the processing cycle, it is necessary to fully consider the procurement time of components to avoid delaying the entire processing cycle due to component shortages.
The processing time for SMT patches and DIP plugins is relatively short, but it is also affected by factors such as process difficulty, order volume, and processing plant scheduling. Generally speaking, sample orders can be delivered in about 3 days, while bulk orders can be delivered in about 7 days. However, this is only a rough estimate, and the actual processing time may vary depending on specific circumstances.
After PCBA processing is completed, electrical testing and reliability testing are usually required to ensure product quality. The length of testing time depends on the complexity of the testing and the precision of the required equipment. Sample testing is usually completed in about 2 days, while batch testing takes between 3-5 days. The testing phase is a crucial step in ensuring product quality and cannot be ignored.
