Convolution of the BOM: How Much Could a Resistor Cost?


Permit me a small history lesson from the perspective of an engineer that has been involved with electronic design and manufacturing for over 50 years. I assembled my first electronic project in the fourth grade, and I fabricated my first PCB in graduate school around 1970. Since then, I have been ...

Maintaining a Competitive Position by Investing in Employees


Leadership psychologist Peter Baeklund posed a question in which a fictional CFO asks his CEO, "What happens if we invest in developing our people and then they leave us?" The CEO answers with his own question, "What happens if we don't, and they stay?"

Convolution of the BOM: How Much Could a Resistor Cost?


Let's evaluate the convolution of the bill of materials (BOM) with all of today's fragmented processes, each with its own jealously protected software. A design engineer (DE) receives a project request to design a circuit. DE opens the schematic capture program and designs the circuit. As part of ...

Why Choosing the Right PCB Vendor is Crucial


All of us have email inboxes full of spam messages that read something like, "Greetings of the day! So glad to know you are desiring to buy PCB's! We always be with you!" While it's never hard to find a deep discount board shop somewhere, it's far better to find the competent shop to get a prototype ...

Inexpensive CAD Software, Expensive Design?


The last 30 years have borne witness incredible changes in the PCB, the backbone of any electronic product design. Package sizes that we thought were small and powerful are now are considered to be big and clunky. We have gone from big through-hole devices to chip scale leadless devices, even at times ...

Why Pay Twice? Getting the Most from Solder by Recycling


If you are part of an EMS company that uses wave soldering, you have already realized that only a small amount of the solder you purchase goes into your assembled device. The vast majority of the solder you purchase becomes solder dross. Most likely you sell it back to either your solder supplier ...

Am I at Risk to Use This PCB?


To properly test for issues with the through-hole process, it is important to understand how soldering occurs. The simplistic assumption is that machines, such as reflow ovens, wave soldering systems, selective soldering systems (or even people) create a solder joint. They do not. In all cases, these ...

Embedded Boards Offer New Solutions


Embedded boards ideally would lower costs while providing more functionality. Motherboards for the consumer market seem to fill this gap, unlike embedded boards, but they lack the longer lifecycles, the support and other features that industrial applications cannot do without. By providing semi-industrial ...

Selecting the Right High Tech Adhesive


Choosing the best adhesive can be a complex process. Carefully selecting the correct adhesive for a job will reduce the number of products that need to be evaluated and increase the likeliness of its success. There are many variables to consider and numerous types of chemistries with different capabilities ...

Improve Crimp Quality to Increase Productivity


High-quality crimp terminations will usually exceed the service life of a product in which they are installed. On the other hand, a marginal-quality crimp termination can cause electrical failures early in a product's life. Since a high percentage of product failures can be traced to poor electrical ...
