  • PCB Assembly Services: Through-Hole Vs. Surface Mount
    by Matric on April 5, 2019 at 2:06 pm

    As electronics have become increasingly embedded in our day-to-day, the manufacturing process for printed circuit boards (PCBs) has adapted. Electronics have become smaller and smaller, and the PCBs that go in those products have had to shrink to keep up. The demand for tiny PCBs has led to a drastic increase in the use of surface mount technology (SMT) -- which has taken over the traditional through-hole manufacturing process that dominated electronics into the 1980s.

  • PCB Documentation to Give Your Contract Manufacturer Up Front
    by Tyler Vasbinder on December 27, 2018 at 10:11 pm

      The decision on which electronics manufacturing supplier to choose can be a difficult one. The outcome of the quoting process often decides who will build your assemblies. That’s why inaccurate quotes are a back-breaker for both OEMs (original equipment manufacturers) and ECMs (electronics contract manufacturers). For example, let’s say you received a quote from a supplier that was higher than your desired threshold. Other than that, this OEM checks all the boxes of an ideal supplier. However, you simply cannot accept a quote in that range. Little did you know; the quote was inaccurate, and the price was more in line with your targeted range. Sure, this could be the fault of the ECM’s quoting process, and that would be on them. But if the OEM did not provide all the necessary printed circuit board (PCB) documentation up front, a missing file could have the same effect. […]

  • RoHS 2 Compliance & Directives Checklist
    by Matric on August 3, 2018 at 4:07 pm

    In 2006, the European Union rolled out a directive restricting the use of certain hazardous chemicals. This directive, Restriction of Hazardous Substances (RoHS), would have a far-reaching impact on the electronics industry. Its restrictions on using lead would send manufacturers scrambling to revise their practices or adopt entirely new ones. Thanks to a follow-up directive in 2011, manufacturers now hustle to meet RoHS 2 compliance. Yes, it’s not a punitive law full of fines and penalties. But if you’re a U.S. company, noncompliance is basically an impassable barrier to entry to the EU trade market. So if you want to do business abroad, don’t mess around -- comply. […]

  • Beware These 6 Printed Circuit Board Layout Pitfalls
    by Matric on July 18, 2018 at 5:12 pm

    Printed circuit boards are vital components of many modern-day electrical gadgets. Printed circuit board layout is made up of numerous layers of copper traces and circuits that help make connections between various parts, as well as plastic and other types of materials that are used to cover and shield the connections from the surroundings. How you design and manufacture printed circuit boards (PCBs) largely determines how well these boards will work in the final product. Unfortunately, layout is becoming increasingly difficult and complicated, as new board circuit designs are being shrunk to fit in electrical devices that become becoming smaller and smaller each year.

  • Why Electronic Component Lead Times Are Rising -- & 3 Ways to Prepare
    by Matric on June 26, 2018 at 3:54 pm

    If your manufacturing projects involve electronics, you’re likely facing the challenge of extended electronic component lead times. Certain parts that used to take 12 weeks to come in are now taking upward of 30 weeks. Some parts even take a full year to arrive. It’s nice news for distributors, who can take advantage of this “shortage” and charge higher prices, but it’s not a good deal for OEMs -- especially considering the importance of fast time to market in today’s need-it-now world. Here’s a closer look at why there’s a shortage of certain components today and what your company can do about it: […]
