The Hermes Standard

---

The Hermes Standard is a data exchange protocol.

Process

Meetings

• Munich 2017 on March 22, the protocol was worked out by a group of industry experts. During the first official membership meeting 16 well-known equipment makers joined the project.
• Productronica 2017 in Munich on November 12, Initial Version 1.0
• Nepcon 2018 in Shanghai on April 23

Partners

• Year 2018 IPC-CFX and Hermes Standards Work Together

Scope of The Hermes Standard Specification

Creation of a modern communication interface which fullfill the existing conditions in a SMT (Surface-mount technology) production line. Amongst other things it replace the existing SMEMA and SIEMENS interface. "The Hermes Standard" includes improvements like transport speed, transport width, the board ID and other things. It should not replace a Manufacturing execution system (MES) but it allows a horizontal communication from machine to machine. It's about machines in the SMT area like Board Handling, Printing, Placement equipment, Inspection, Testing and Reflow soldering machines.

The Basic Idea

For each PCB, an information record is passed to the machine by the previous station upon handover. When the machine has completed its own processing, it passes the PCB and the information record to the next machine. The own editing data of the machine is not included in the information record. A special requirement is placed on the reflow ovens which cannot stop the process. If the PCB cannot be handed over then there is a jam at the outlet. In this situation, an informatics data set can not be assigned to the assembly because the jammed PCB's are identified by the sensors as one.

Improvements

• Replace the electrical SMEMA interface as specified in [IPC_SMEMA_9851] . This saves on the wiring on the machine and the incompatibility of different plugs what often happens today.
• The communication of an unique identifiers of the printed circuit board (PCB) and the transmission of equipment identifiers of the first machine. the PCBs can be traced from the beginning of an production line until the end.
• The Transfer of Barcodes, which saves additional and expensive Barcode reader systems within the production line.
• The Transfer of Product type specific information (Length, Width, Thickness). This information is often captured or detected by additional light barriers today.
• The Exchange of the conveyor speed, to avoid transfer problems due to different belt speeds. Currently this parameter is solved by an analog signal or a special interface if required.
