PCBA was completed on time and according to the requirements. The price and shipping cost were reasonable. I recommend ELECROW for this type of work. This project involved low-noise power supply boards based on Texas Instruments TPS7A3301 series negative LDO regulators. The board was designed as a low-noise drop-in replacement for LM7905 regulators. Each regulator board was separated from the panel and packed in an individual antistatic bag.
