Virtual Training

In this day and age everyone is working remotely and adapting to the times. TJ Green is no different which is why we now offer a variety of online technical topics for engineers to continue to learn and grow. These classes provide all the same high level training as our public courses but from the comfort and convenience of your (home) office.

Here are some of the benefits of our virtual training:

  1. No travel expense. Budgets can be tight and training can be hard to get approved but not having to add on travel and lodging is a huge plus.
  2. Less down time. Let’s face it. We are ALL busy and losing a day for training and sometimes an additional day for travel is just not practical. With sessions being scheduled over a few days you can still attend to all your important professional and personal responsibilities and still get the training you need.
  3. Easy to attend. Sessions are hosted live using GoToMeeting which allow for real time question and answers and all class notes are online for you to download at your convenience. You have a full week after class to review any of the session recordings and notes. (session recordings are available for review the same day so if you can’t attend you can still keep on track for the next session)
  4. More options. With not having to reserve a space and place so far in advance we are able to continue to add more classes to the schedule with means easier scheduling and more learning for you.

Copper and Gold Wire Bonding

wire bondWire Bonding is a welding process that is the dominant chip interconnection method. More than 15 trillion wires are bonded annually. In the past, gold wire was the dominant material in use, but in 2015 copper and palladium coated copper wire captured more than 51% of the total market. Copper provides benefits in cost, improved conductivity, stiffness and reliability. However, it is significantly harder than gold and achieving a robust, reliable process is more challenging. With the high productivity and growth rate of wire bonding, it is one of the most reliable manufacturing processes. Achieving high yields requires rigorous attention to details and excellent statistical process control. Wire bonding high-volume lead-frames often generates defect rates below 10ppm, this presents a significant barrier to entry for any process competitor, but copper is meeting the challenge in high-volume manufacturing.

This course is intended for wire bond process engineers, technicians, quality control engineers and managers.

Design and Test of Non-Hermetic Microelectronics

non-hermeticPackages made from polymeric materials as opposed to traditional hermetic materials (i.e. metals, ceramics, and glasses) require a different approach from a design, production, testing, and qualification standpoint. The problem is now one of moisture diffusion through the barrier and package interfaces. Fick’s law of diffusion and the interaction of moisture and other gases with the plastic package, with or without a cavity, is of primary importance.

This course begins with a brief overview of hermetic packaging and associated testing methods that have been developed over the years, some of which are applicable to cavity style non-hermetic enclosures. Then the focus is primarily on the materials used to build non-hermetic packages and the variety of testing methods available to evaluate the non-hermetic package. A review of the techniques and methods to evaluate a “non-hermetic” approach is discussed with a special emphasis on cleaning of the device prior to encapsulation and alternate test methods to evaluate reliability. Click here to see the full outline.

The course is intended for process engineers, designers, quality engineers, and managers responsible for design, test and production of cavity and non-cavity style non-hermetic packages intended for use in high reliability military and Class 3 medical implants.

Microelectronic Packaging Failure Modes and Analysis

failure modeThe design and packaging of microelectronic devices such as hybrids, RF microwave modules, Class III medical implants and other types of packaged microcircuits intended for high reliability systems is a critical aspect of reliability engineering. This course is intended to review and highlight the typical kinds of microelectronic packaging related failures that occur during manufacturing, qualification and the unfortunate field failures. FA (failure analysis) tools and techniques that are utilized to understand root cause of failure and guide corrective actions will also be addressed by experts with years of experience working in FA labs.

The instructor shares his years of experience related root cause FA investigations of microcircuit packaging defects and failures. Mismatched CTEs and poorly designed packages geometries often lead to mechanical failure at the die and substrate interface or cracking at the heel of a wire or ribbon bond interconnect. Careful delid, visual inspection followed by SEM and EDAX/Auger are required to identify root cause. Reliability engineers must be cognizant of the full range of FA tools available to diagnose failures and, resist the temptation to rush to judgment, which often happens destroying valuable evidence along the way. The instructor will review real world specific examples of packaging failures and resultant FA analysis and problem resolution. Click here to see the full outline.

The course is intended for FA engineers, component engineers, reliability engineers, design, quality and process engineers involved in microelectronic packaging.
