Testing Todd: Preparing Employees for the Long Haul

Rebuilding our workforce after the COVID-19 pandemic has been a challenge. Nationwide, we downsized to combat market conditions and ultimately lost good employees due to either the virus or them finding new work elsewhere. That has left some rather large gaps in our manufacturing workforce. Human resource departments are scrambling to find new employees, while the manufacturing base struggles to educate and bring new employees up to speed. If not handled correctly, this scenario could create even greater problems for manufacturers.

While automating menial or repetitive tasks is one way to quickly fill the gaps at low- or entry-level positions in the workforce, filling more complex roles can be more challenging, and is where many companies fall short.

Companies find new candidates, send them into the workplace jungle, and assign them a supervisor who instructs them on their tasks or duties. Realistically, new employees are often overwhelmed and may struggle to master the assigned tasks. In many cases, the supervisor is also over-tasked with other duties and responsibilities and cannot provide the over-the-shoulder experience that is required for good oversight.

Employees learn in different ways. Some of them are visual learners, grasping new tasks and instructions on the fly, while others need to read instructions and commit them to memory. This is why long-term success for employees relies on a robust training system that connects to different types of learners.

Those involved in quality management systems will see that this is nothing new. They know that having a truly functional training system is essential to guaranteeing the long-term success of employees. An effective training system must do more than just satisfy a requirement.

Developing strong, documented processes is a must. They must be “ready for pickup” by new employees so that they can learn and understand the process in which they will be involved. Furthermore, the work instructions associated with the tasks must be mature and bulletproof.

The overall training process can break down when a supervisor, who may not be well versed in the process, assigns another employee the task of showing the ropes to new hires. In my experience, this is not a good practice. This is when missed steps or manufacturing-floor “voodoo” may come into play, setting up the new employee to fail or become the fall guy.

Here are some tips that can help you achieve long-term success in filling either vacant or new positions as workforce conditions improve.

  • Document your processes and, at a minimum, review them annually.
  • Designate trainers for each department and, if necessary, for each task level.
  • Train the trainers. Make sure they know the process inside out. Be sure to document employees’ knowledge.
  • Train new employees; don’t just show them the ropes. As I mentioned, effective training that utilizes different ways of learning will ensure long-term success of new employees. Document their knowledge level and then review (and document) it again 60 to 90 days after hiring as a way to validate their progress. Finally, discuss with them any concerns you may have.
  • Review an employee’s knowledge retention at least annually. This ensures that no irregular habits have been introduced into the process and that employees are progressing well. Perhaps they have mastered the tasks and are ready for a new challenge. You can backfill their current position and move them into a more challenging role in the company.

Summary
The post-pandemic years have been challenging. Effectively rebuilding the workforce for the long haul requires some fundamental steps, such as training new employees and reviewing their knowledge over time. Whether this is new to you or just a review of standard practice, I hope you now have some tools to help your organization grow effectively as you face challenges ahead.

Testing Todd: Coming Back to Life—Design Recovery

12-29-2022

Although iconic, when I say “coming back to life,” I’m not talking about a Pink Floyd song, but rather about printed circuits. Bare boards have been in production for decades—from single- and double-sided breadboards to the impressive multilayer designs of today—and we all agree that the PCB is here to stay. With today’s technology, designs are archived and realistically available forever. However, much of the legacy product of decades past is long forgotten. These rugged PCBs have been in service for years; their spare parts are full of dust on a forgotten shelf, ultimately obsoleted and scrapped.

Testing Todd: Decision Time—Invest or Delegate?

As they struggle to keep delivery times competitive, manufacturers are faced with a decision: Do I invest, or should I delegate? To stay competitive, a large percentage of capital must be slated for PCB manufacturing equipment. This is understandable as that is where the revenue is generated. Newer equipment begets higher technology builds and thus, more revenue. The drawback is knowing how to get this product out the back door. There are delays in electrical testing due to long test times using equipment that is not best suited for today’s demand.

Historically electrical test has processed product with passive inductor features without really knowing what they were, other than causing continuity threshold violations. This is usually due to the long traces that exhibit higher resistance than the 10- or 20-ohms threshold. Typically, these have been delaying traces or heater traces. Usually, a waiver of allowance is made for these high resistive traces and business carries on as usual.

Testing Todd: Breaking the Void

09-07-2022

Electrical test is best known for identifying routine opens and shorts. But what has plagued ET, and manufacturers in general, is the barrel void. These voids are breaks in the plating of the drilled barrel that result in circuitry “opens” that pass through the stackup from one layer to another. In some cases, the break in plating is severe and results in an immediate open condition that is detected during electrical test. However, certain plating anomalies can be present that will go undetected during standard ET. What we must remember is that electricity must follow Ohm’s Law no matter what conditions exist. That is: V = I x R, where V = Voltage, I = Current, and R = Resistance.

The New Electrical Test—Riding the Wave

11-22-2021

Many years ago, when electrical test (ET) was necessary on a bare printed circuit board (PCB) you would build a dedicated fixture with spring pins and mount the box fixture to a machine interface and perform the test. However, back then there were no preconfigured netlists, and the machines were only capable of “learning” the board. This was known as the “self-learn” or “learn comparison” test. At the time, all you could do is prove that all the boards of the test lot were the same. The risk was that if there was a film defect and all boards had the same fault, the test would still pass even though all boards were defective.
