Wire bonding, as shown in Fig. 1, and die shear strength training are inextricably intertwined. Die shear strength is a demanding aspect of wire bonding to assure top quality and reliability to comply with Mil STD 883, Rev. G or Rev. F. In particular, wire bonding and die shear strength testing play prominent roles for […]Continue Reading...
IoT is the hottest topic in the marketplace right now. It’s coming into virtually every person’s life in terms of equipment and devices being used. In effect, IoT is automation coming to your doorstep, your home, car and coming into every workplace. Printed circuit board (PCB) design software, more commonly known as “tools,” is the […]Continue Reading...
Micro BGAs are proving exceedingly popular these days. These small packages are not only populating conventional PCBs that continue to increase in complexity, but also the smaller circuit boards for IoT and wearable devices. The micro BGA package is more compact than other SMT devices and hence, has a shorter contact length from the device […]Continue Reading...
IoT devices remain in their infancy, with a lot of questions being asked and experimenting going on. Radio frequency, or RF, is one technology that IoT companies and startups are dialing into to advance state-of-the-art IoT and, in doing so, increasing profit margins for their IoT products. In some cases, there are a lot of […]Continue Reading...
ATE PCBs can be up to 0.187-inch thick or even 0.25-inch, with a high layer count that includes a number of ground and power planes and have a lot of gold on the surface (typically 50 micro inches, ENIG) on the tester and DUT pads. The size of the board along with the amount of […]Continue Reading...
Just like the big boys (meaning conventional printed circuit boards), IoT PCBs fall under the categories of Class I, II and III. Earlier, I noted that Class I IoT PCBs are pretty routine; those end applications cover virtually every consumer wearable you can think of. Class I IoT PCBs don’t demand a great measure of […]Continue Reading...
