Committed to Manufacturing Solutions

The process of soldering electronic components to a printed circuit board is referred to as SMT assembly technology (PCB). In this process, tiny amounts of molten solder paste are used to connect component leads to pads on the PCB surface. The SMT assembly procedure is primarily comprised of the following steps: solder paste printing, chip mounting, reflow soldering, cleaning, inspection, and rework, all of which will be discussed in detail below.

Michaela ★★★★★

The assembled PCBs that were delivered worked flawlessly. The component placement is excellent. Mis wang, the WINOW engineer in charge of our project, and I hit it off right away. She asked pertinent questions to ensure that the project was properly completed. We had a very nice, short, and to-the-point conversation.

Herbert ★★★★★

This board is required to charge my robotic platform's lipo batteries (rover). First-time order with excellent communication throughout the ordering process, manufacturing progress, and tracking up to delivery. Very good price, especially for the first order with a credit for a discount.

Al Lemke ★★★★★

The boards arrived yesterday, and assembly has begun. Excellent solder wetting, clean line definition, and drill holes that are precisely in the center of the via lands.
Please convey my gratitude to everyone who created such wonderful boards.
