Manufacturing Line 101: The basics of Assembly Line Machines Machines
A typical assembly line contains, at a minimum, the following items:
Board Loader
Blank PCBs are stacked here for use with the screen printer. This is preferable to manual insertion due to a higher speed capability.
Screen Printer
Solder paste is applied to a blank board through a screen and wiper. Paste may be RoHS (Lead Free), or SnPb (Leaded), with no-clean or other fluxes. Typically, No Clean satisfies most customer requirements. Lead and Lead Free is visually segregated by use of different color schemes on the stencil, blade, and paste itself.
High Speed Placement
Also known as a ‘chip-shooter’, the smallest and most plentiful parts are placed first. This operation is quite fast! A modest machine operating at capacity can place over 50,000 parts per hour!
High Flexibility Placement
All remaining IC’s, connectors, BGA’s, or odd sized parts are placed by a high-end placement machine. These flex placers may accept reels, tubes, trays, any form parts may come (but not bulk!).
Convection Reflow Oven
Thermal profile is key to success! Using a high amount of reflow zones, Aimtron can put more boards through at a faster rate, while preventing any thermal shock.
Conveyors:
Between all machines are transport conveyors. They can signal each other to pass a board to the next station when ready.
Post-Line operations include Automated Optical Inspection, and Reporting.
Aimtron takes great care to prevent problems from occurring on the line. It is a lean concept to prevent errors at their source. Our combination of experience, passion, and procedure helps us reduce overhead cost to you, and waste in the process.
Are you ready to experience the Aimtron difference?
