Designing and manufacturing electronic boards

If you prototype printed circuit boards , how can you ensure that laminates and prepregs you used will match those used in offshore volume production? As an industry, those of us involved in designing and manufacturing electronic products can all agree that we now live and operate in a global supply chain environment. Since a lot […]

Why SMT?

Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs). An electronic device so made is called a surface-mount device (SMD). An SMT component is usually smaller than its through-hole counterpart because it has either smaller leads or […]

PCB production Steps

PCB Etching Process All PCB’s are made by bonding a layer of copper over the entire substrate, sometimes on both sides. Etching process has to be done to remove unnecessary copper after applying a temporary mask, leaving only the desired copper traces. Though there are many methods available for etching, the most common method used […]

Why the etch pads are not big enough for vias

Now C-Alley is using the leading edge technologies such as ball-grid arrays (BGAs), chip scale packaging, flip chips, QFNs, DFNs, and others. It shines x-ray radiation through a component package like a BGA to view images including wire bonding, solder joints, and solder defects, if any. Standard x-ray inspection is used for simple applications, whereas high-end […]

De-soldering components (through-hole and SMD)

SMT parts have many advantages over their older through hole ancestors, namely: smaller size, lower cost manufacturing costs, and less likelihood of obsolescence. However, an often overlooked advantage is the ease at which surface mount components can be soldered and desoldered. At first this might seem like a controversial subject, but it isn’t to engineers […]
