BSA offers both on-line assembly and packaging services for simple tasks, and more complex, off-line assembly and testing options to meet specific requirements. The company can handle everything from basic assembly and packaging to more intricate processes like hotplate welding, ultrasonic welding, and heat staking. They also offer customised manufacturing, transportation, and delivery services. 

Here's a breakdown:

On-line assembly and packaging:

This refers to straightforward assembly and packaging processes that can be integrated into a production line, likely for simpler products or when speed and efficiency are paramount. 

Off-line assembly and testing:

This covers more complex assembly procedures, potentially including specialised techniques like hotplate welding or ultrasonic welding, and more rigorous testing procedures. 

Customisation:

BSA can tailor the assembly process to meet the specific needs of a client, ensuring high-quality output.
