when it comes to sourcing parts for your printed circuit board, there is a difference between who you buy from there as well. Let’s take a look at some of the differences between domestic sourcing vs international sourcing in the components you need for your PCB builds.
If you work with a reputable and experienced manufacturer, you’ll have access to a broader range of standard PCB sizes than 1.57 mm. If you need a customized board thickness with precisely controlled laminate thickness for controlled impedance, a reputable manufacturer can give you access to a range of laminate options for your custom stackup.
Each of these areas must be carefully managed in order to assure that the parts needed for building your board are there when the board goes into manufacturing. Let’s take a closer look at these five areas of concern for supply chain management in the electronics industry.
Some materials and components will more stringent shelf-life specifications than others. If those specifications aren’t followed, it could result in a lot of problems with the production of the board. Here is some more information on the shelf life of printed circuit boards as well as their building materials and components, and how your contract manufacturer should be working with them.
My father always used to say, you can fix most problems with bungee cords and duct tape. Unless you plan on duct taping your components to your PCB, your boards will have to go through a manual or automated soldering process. This is where it is important to understand the factors that affect PCB solder joint strength.
Designing a PCB that has RF circuitry on it can be a real shock to a layout engineer if they aren’t prepared for it. PCB shapes for RF may be odd-looking, and the design constraints may end up breaking the standard rules that you are used to. Here are some RF PCB design guidelines that can help.
