- Welcome to the training module on MEG-Array® Connector System. This training module introduces a high speed Mezzanine MEG Array ® connector, its features and applications.
- The FCI MEG-Array Connector system is used in mezzanine applications that require high speed capability and/or high density. The unique Ball Grid Array termination is well proven and reliable. The MEG-Array connector is based on contacts in a fifty thousandths of an inch square array. It is available in contact patterns of 81, 100, 200, 240, 300, 400, and 528 positions, and in mezzanine stack heights from 4 to 14 millimeters.
- Meg-Array connectors have a bandwidth of up to 10 gigabits per second. The BGA solder joints have a demonstrated solder joint reliability in excess of 22 years and the connector system meets Telcordia requirements.
- Though the Meg-Array uses a very small contact system, it is big in performance. The contact structure provides for two points of contact when mated together, resulting in excellent contact reliability.
- This table shows currently tooled versions of Meg-Array plugs and receptacles and the various pin counts as well as stack heights that can be achieved.
- In next few pages, we will look at some applications where the FCI Meg-Array can provide a good connector interface solution. In some servers the memory or some functional options may be in the form of an add on board. The Mezzanine supporting an option board is shown here being connected by the FCI Meg-Array.
- Similar high speed and high performance mezzanine applications can be found in Switching and Transmission equipment such as large switches and Routers.
- Optical transmission equipment can be an excellent place to look for Meg-Array applications. Along with typical mezzanines, The FCI Meg-Array system is commonly used as an interface for optical transponders as well as parallel optical links, sometimes called Paroli modules. Here you see examples of these two types of products. The FCI Meg-Array is shipped in Tape and Reel packaging with an optional vacuum pick up cap, that doubles as a contact protector, an example of which is seen in the crème color Meg-Array mounted on the Optical Transceiver on this page.
- The high pin count of the FCI Meg-Array system works well in medical high end imaging applications such as CT Scanners, MRI, and Cardiovascular X-Rays as well as in Radiation Oncology ECG analysis equipment.
- The FCI patented BGA technology allows the products to achieve high density and high performance. Some of the advantages of Ball Grid Array technology include the lower applied cost when compared to press fit termination. The ability to use reflow processing allows you to terminate the connector simultaneously with other surface mount components. BGA termination helps in high speed applications since vias can be eliminated or minimized. Routing becomes easier due to minimal vias, and double sided connectorization is possible since there are no parts of the connector protruding through the board.
- FCI’s patented BGA design assures perfect solder ball location. Alternative designs provide no guidance for ball position, and don’t always assure a good connection between the solder ball and the terminal.
- Another advantage to BGA technology is the ability for the solder balls to self center on the circuit board pads during reflow. This ability can compensate for placement errors up to 50% of the pad size.
- Additionally, the solder balls will help to self level the Meg-Array connector, compensating for small variations of pad height or slight warpage of the circuit board.
- FCI verifies the coplanarity of all of the solder balls on each connector as it is manufactured. In addition, FCI has contracted an outside lab to evaluate our solder joint reliability based on IPC standards, and determined that The Meg-Array would be reliable for over 22 years.
- In summary the FCI Meg-Array connector system has proven reliability for over 12 years, and laboratory life testing shows that it should have solder joint reliability in excess of 22 years. The FCI patented ball grid array and mating interface with two points of contact assure high reliability and excellent electrical performance for many years of product service.
