PTH Assembly

PTH assembly is referred for through-hole assembly. Crosspoint Technologies is aligned with skilled stuffing team, customised forming tools along with Automated Selective soldering machine for proto type assembly and Wave soldering for low and medium volume assembly

Cleaning

Assembled PCB cleaning is a critical process in the EMS industry to ensure the reliability and quality of electronic components and products. Cleaning ensures the assembled PCBs are free from contaminants promoting solder flow connections, which interns ensures the solderability. Hence, Crosspoint Technologies added Automatic Aqueous cleaning machine in assembly process to ensure improved product reliability. 

Mechanical Assembly

Mechanical assembly is a critical process, where mechanical components are assembled to create final product. Mechanical assembly includes cable assembly (assembling cables and Wiring harness), Mechanical component assembly (such as enclosures, brackets and fasteners), Precision Assembly (such as connectors, sensors, switches and other critical components) and different types of Press-fit connectors & Press-fit components. By leveraging mechanical assembly capabilities, we can help customers produce high quality products efficiently and reliably

Functional testing

Crosspoint Technologies has dedicated bench setups for doing functional testing of the assembled boards. The setups have all the necessary instruments for testing and debug operated by a dedicated team of test engineers. Functional testing at the EMS site helps in finding any issues and fix them quickly. This saves a lot of time for the Customers and helps with faster TTM
