Meaning
Throughput rates measure the number of electronic parts an automated machine can mount onto a circuit board in a given hour. The component placement speed is a limiting factor in the production of consumer electronics and industrial controllers. It is determined by the movement of the robot arm, the vision system check and the time taken to pick each part from its feeder.
Machine Performance
High end pick and place machines utilize multiple nozzles and advanced motors to maximize their efficiency. If the component placement speed is high, it allows the entire assembly line to produce more finished boards per shift. However, the machine must still maintain a high level of precision to avoid misaligning the parts on the solder pads.
Accuracy Tradeoff
Increasing the rate of production can sometimes lead to a higher rate of defects if the machine cannot keep up with the vibration or the heat generated. A very high component placement speed may cause small parts to shift before the solder is applied. Finding the balance between speed and quality is essential for maintaining a high production yield.
Capacity Planning
Manufacturers use these speed figures to determine how many assembly lines they need to meet their annual sales targets. If the component placement speed of the existing equipment is too low, the company may need to invest in faster machinery or run extra shifts. Accurate measurements of this speed allow for better scheduling and more reliable delivery dates for customers.
