Peter BigelowSupply chain fatigue taking hold? It’s all in a day’s work.

I can’t think of a more exciting time than now, especially for the PCB industry. Risk has always been a friend and catalyst to our industry. There has rarely been more types of risk, and never as varied, for all industries and companies, large and small, to navigate. As varied as it may be, all those challenges seem to boil down to three basic categories: technology transfer; geopolitical posturing; and logistics fatigue. The single common denominator to all? People.

My bet is that dealing with new technology, and the transfer of that technology to displace or enhance tried-and-true methodologies, is the easiest for our industry to wrap itself around. The risk and reward of new technology is well understood. It has been the hallmark of how and why we are in business and prosper. However, for those in the auto industry, which has over 100 years of understanding of mechanical and internal combustion equipment, the dawning of hybrid and electronic technologies to propel a vehicle, let alone control and monitor performance – with or without a driver – brings nothing but risk. For our industry, supplying this transfer from mechanical to electronics creates a different type of risk. Now “consumer” products must be as rugged as the toughest military or aerospace application, or even more so, because the sheer number of lives at risk are greater and the operating environment less controlled.

Mike BuetowHave all the supply chain tools companies have developed and their customers put into place worked? We are about to find out.

I’ve been a journalist through four PCB recessions and counting. By my estimates, we are about to hit number five.

According to ECIA, lead times for most types of passives and actives are down since last winter. Likewise, component distributor TTI reports similar trends. Its weekly reports show demand for most types of parts are either stable or dropping over the past several months.

Semiconductor capital equipment and device revenues are now forecast to contract this year.

And while researchers disagree whether semis are leading or trailing indicators, most forecasts from the leading economic nations and regions are subdued or tilting down too.

Mike BuetowThe headlines of late have been filled with reports on the pending US ban on domestic companies from conducting business with Huawei.

In submitting the order, President Trump cited cyber-warfare, espionage and threats to US national security as rationale for the ban.

Less noted: the impact on bare board suppliers from China. After all, the executive order “prohibits transactions that involve information and communications technology or services designed, developed, manufactured, or supplied, by persons owned by, controlled by, or subject to the jurisdiction or direction of a foreign adversary” as determined by the Commerce Secretary.

So, while Huawei is a $100 billion company, larger than IBM, Sony, Hitachi, Panasonic and all but a few other tech firms, the declaration could have tentacles that reach far beyond the Chinese OEM. Even if all the defense industry primes, for instance, buy all their boards onshore (doubtful), many others do not, including the financial markets and key industries such as nuclear, power, and so on.

Bob WillisA lack of compression can be seen nondestructively.

This month we look at crimp connections.

FIGURES 1 and 2 show examples of simple compression connections. Figure 1 shows an excessive length of stripped wire within the crimp termination and a total lack of any compression, which should be easy to see on the wire bundle from the point of entry to the point of compression. Figure 2 lacks compression of the connector, and the stripped wire is barely within the barrel of the connector.
