When manufacturing printed circuit boards a defect can occur when the metal from two different nets inadvertently gets shorted or bridged together with solder. This particular defect can be small and difficult to find, but the short circuit it creates causes big problems. These can include intermittent connections, false test results, or traces and component leads that burn through. We’re going to take a closer look at this problem and discuss some PCB design methods on how to prevent solder bridging.
One of the primary goals of manufacturing is to build a quality product, but there is more to quality than what you see on the production floor. Quality also means planning to avoid those problems and defects that can derail the delivery of a dependable final product.
When a printed circuit board is built, it’s also beneficial to have added assurance, except in that case we’re looking for problems in manufacturing. Not that we expect to find any defects, but we want to ensure that if a problem does come up we can find and correct it efficiently. This PCB defect detection process takes place with both the bare boards after they are fabricated and the fully assembled circuit boards, both of which we will examine in greater detail below.
Getting a PCB prototyped with speed and precision is an intricate process to manage because the design must also be prepared for eventual long-term production. Balancing the electrical performance and the manufacturability needs of the board requires a lot from both the PCB designer and the manufacturer during the prototype phase. Here are some of the requirements that you should be familiar with so your board can progress successfully through the rapid PCB prototyping phase of its development.
When routing a trace on a printed circuit board, you can have some of the same difficulties. It can be challenging to figure out the best path for your routes through a multicolored maze of traces. Thankfully some of the tricks that we used to do with maps, like highlighting the route that we wanted to focus on, are also available to us when routing traces on a circuit board. Here we’re going to look at several PCB routing techniques that you can use to find the best course to your destination.
Printed circuit boards go through an intense process of design and manufacturing to function as required. This process involves incredible amounts of engineering expertise to produce the final result, and each step has multiple steps that must be followed meticulously for the board to operate correctly. The materials used for the manufacturing of the circuit board are a perfect example of how many details are being considered. They can vary according to the electrical performance, thermal conditions, and physical environment that the board will be operating in. Here are some particulars about PCB material properties, and how they can impact the manufacturing process of the circuit board.
