What does Surface Mount Machine do?
Surface Mount Machines are also called Pick-and-place machines or SMT Component Placement Systems.
These machines are robotic machines used for placing Surface Mount Devices (SMDs) onto Printed Circuit Boards (PCBs).
These machines are commonly used because of the high precisions, several use cases/applications, and the variety of electronic components that can be used on them.
Automatic Pick-and-place Machines
Automatic SMT machines replaced the semi-automatic models. The automatic model was improved to make the transition of the leap from manual to fully automated SMT machines.
Among many other things, automatic SMT machines are fully equipped with pick and place centering methods, as well as improved machine capabilities, in the areas of repeatability and accuracy.
Placement Speed
The speed at which the pick-and-place machine works is very important. You want to consider this first before any other thing because it is one of the important features that make the SMT machine work as it should.
Also, you need to understand that the placement speed has to do with the speed or rate at which the SMT machine picks up the SMT components inspects the components before placing the components on the Printed Circuit Board (PCB).
The other important factor you want to consider about the placement speed is the standard rating of IPC 9850. This is the standard used by many SMT manufacturers to rate the speed of the pick-and-place machines. Besides, the IPC 9850 speed or rating standard has to do with the general guidelines for the circuit board arrays and the part mix.
The rule of thumb is for you to devalue any figure that the manufacturer may have given. The devaluation is important because the speed quoted by the manufacturers is usually lowered by 30% or 40%.
Therefore, you will get an accurate value or figure of the potential rate or speed of the SMT machine if you make some divisions. The best way to divide is by devaluing or reducing the placement rate of the machine’s rate by 30%. This way, you will have a clear speed value that the SMT machine can deliver.
