Micro Technologies in the PCB Assembly Industry

Custom manufactured micro screws and other forms of miniature fasteners are becoming increasing popular in the technology manufacturing and other micro manufacturing industries. The extremely small size of these products allows flexibility in many specialized products such as computer technologies, automotive parts, medical instruments, and more.

Custom manufactured micro screws are a staple in the modern consumer and industrial industries, as they allow for more and more innovation and smaller technologies. Breakthroughs such as medical nanotechnologies rely on specialized small scale manufacturing such as custom manufactured micro screws. Here is some important information on these tools and what they are capable of. Micro manufacturing has especially made strides in the PCB assembly service. PCB assembly service, including circuit board assembly, prototype assembly, and turnkey PCB assembly, relies heavily on tiny tools that can quickly assemble electronics with minimalized human error.

Screws with a reduced diameter will consequently displace a smaller amount of plastic material while simultaneously minimizing stress. They have a double lead high and low thread, with the high thread being 30 degrees, which greater minimizes material displacement and positive thread engagement.

SEMS screws are a quick, durable, and easily adaptable option which is useable for many different applications, because they combine two individual parts into one low cost fastener.

You may choose from two main types of thread lockers currently available. Inert thread lockers, which may also be referred to as prevailing torque, will create a secure fastening lock resistant to vibration and shock related slipping. The other form of thread locking is reactive thread lockers.

The torque required to start relative rotation between the mating thread and a locking fastener with no axial load on the screw is known as breakaway torque. This form of torque will change with reuse and is referred to as the first off, fifth off, forth off torque and so on. Breakaway torque is due to the locking element.

Pre load is a measure of the axial load that is imparted on a fastener, and a result of the measurement of the applied seating torque (typically measured in pounds per square inch) will create tension in the fastener. The pre load is commonly accepted to be around 85% yield strength.

More than 200 billion fasteners are manufactured and used annually in the United States. That makes the net worth of the United States screw, nut, and bolt manufacturing industry and PCB assembly services industry $30 billion as of last year. The industry as a whole employs over 130,000 people.
