Meaning
Machine to machine communication protocols for surface mount technology lines replace the traditional electrical signals used for board handover. The ipc hermes 9852 standard provides a method for passing circuit board data such as barcodes and dimensions between adjacent machines in a production line. It utilizes TCP/IP and XML to allow for more complex data transfer than the older SMEMA interface.
Board Tracking
Digital identifiers follow each assembly as it moves from the screen printer to the final inspection station. Because ipc hermes 9852 carries the board ID and slot information the downstream equipment can automatically load the correct recipe. This automation prevents errors caused by operators manually selecting programs for different products.
Protocol Migration
Upgrading a line from legacy hardware requires the installation of converters or the updating of machine firmware. Most modern equipment manufacturers provide native support for ipc hermes 9852 as the default interface for board handling. The transition allows for the capture of more granular data regarding the movement of materials.
Line Synchronization
Coordination between machines ensures that the speed of the conveyor matches the processing time of the slowest station. If a machine stops for maintenance the ipc hermes 9852 signal informs the upstream units to pause the flow of boards. This prevents physical damage to the assemblies and reduces the risk of mechanical jams.
