When producing large volumes of PCBs (Printed Circuit Boards), multiple individual boards are often combined into one large panel. This panelized form is then processed through automated SMT production lines to improve efficiency and reduce costly machine idle time.
When deciding how to connect the boards in a panel, you must also consider how they will be separated later. Otherwise, you might end up with a panel that’s easy to assemble, but difficult to de-panel.
The 5W1H (Five Ws and One H) method can be considered both a problem analysis and solution tool. However, it’s better viewed as a structured way to think about and describe problems. It helps us look at issues more comprehensively, explore possible causes, and take corrective actions. Although the method is somewhat simple, it’s easy to remember and very practical. Sometimes it’s also called the Six Ws method, and some people even extend it into 5W2H by adding another “H” for “How much” or “How many.”
When you think about it, doctors are really just engineers who work on people instead of machines. Their methods and processes are surprisingly similar. So, engineers — you’re basically doctors too, just with different patients!
Einstein once said, “An expert is just a trained dog.” Workingbear can’t really argue with that. In fact, Workingbear believes doctors are, in essence, engineers. The main difference is what they work on: engineers deal with non-living things like machines or products, while doctors deal with living humans — that’s about it.
MOQ stands for Minimum Order Quantity, meaning the smallest number of items a supplier is willing to sell or produce in one order. In most parts sales, especially for less common items, there’s usually an MOQ requirement. Why? Because no manufacturer will set up an entire production line just to make a handful of parts.
Once a production line is set up, it must produce a certain volume to make economic sense — since running a line requires manpower, materials, and support resources that can cost far more than most people expect. Of course, if you’re willing to pay an extra USD 2,000 setup fee just to make one USB drive, no one’s going to stop you!
SPI stands for Solder Paste Inspection. If we’re talking about the actual inspection equipment, people usually add “machine” after SPI. But in most cases, when you mention SPI in an SMT factory, everyone just assumes you’re talking about the inspection machine.
So what’s the real purpose of SPI? What exactly can it do for us? And why are more and more SMT lines adding SPI machines these days?
