The rule is that the board’s longest side rests on the conveyor, to minimise the bending of the board. The information we need to correctly configure the machine comes from the datasheet of the component, but also experience plays a major role here.įinally we define the board position on the machine. The speed of the mounting head depends on the component’s dimensions, weight and material. When we change reels, again the first 3 components are measured. Not each and every component is measured, for each new reel, the first 3 parts are measured, and when measurements are within tolerances, the complete reel is accepted. Our machine is capable to measure electrical values for resistors, capacitors and diodes, and based on the measured values compared with set values the machine will accept or reject components to be placed. At its inception, Gerber emerged as a standard that could guide the production of circuit boards among Engineers. A Gerber Setup dialog provides you with tools to completely configure your Gerber file output options. For new entries, we copy most of the data from the PCBA Visualizer database, and enhance this with instructions for the machine.Įxtra information we add is the polarity according to the machine rotation conventions, dimensions of the part and electrical values. Placing details like this on a mechanical layer is a good place for such data, Or in a text file.
Starting from a BOM file, already prepared for our PCBA Visualizer tools we start this process.Īll parts mounted earlier are available in the machine database and are recognised by their MPN number.
The control centre of our Pick & Place machines, called M圜enter has an own database of components with machine-specific instructions for each component to be placed. Starting from a prepared data set, ready PCB’s, stencils and components mounted in feeders, we will now create proper instructions for the Pick & Place machines.
