As the printed circuit board’s physical size became smaller in one or both directions, it quickly became an issue for both the raw PCB supplier and the contract manufacturer to manage the parts on certain equipment. Processes like routing, electrical test, and packaging added cost to production for either time or scrap. Fallout was an issue that recovery was not possible.
When we look at where we are today vs. 1980 or earlier with technology, it is truly amazing. Just think about an appliance, for example, the household refrigerator/freezer. It used to be that you opened the door, looked inside, found what was needed, and closed it. I can hear my parents yelling, “shut the door,” like all the cold is coming out and everything will spoil. Settings were cold/coldest on a dial you turned.
Printed circuit board (PCB) production has used standard panel sizes, such as 18x24 inches, to produce multiple PCBs at the same time, along with several other panel standards. A panel containing single format PCBs typically would use routing as the method of removing the single pieces from the master size.
What is a void in the printed circuit board (PCB) world? A void is an un-plated area within the hole wall of the PCB drilled plated hole. Voids in hole barrels can be equally problematic in all types of PCBs. The number of layers contained within the PCB plays a part in the cost of the completed circuit board. The more layers within the card the more cost is added for manufacturing. However, a two-layer part can also be expensive to scrap.
Dating back to 1952, we are industry leaders and experts in all things printed circuit board (PCB) related, rigid PCBs, flexible circuits, and rigid-flex circuit boards combined, we know all the options and the difficulties in the fabrication processes. In this blog, we will focus on flex and rigid-flex PCBs what you should know and what to look for regarding the design and layout, as well as the importance of a successful data set and what is needed to prevent delays in engineering and manufacturing.
I love looking at data. Sounds weird, right? I guess it is because I have been working in the industry for so many years. I have seen the technology changes, and I just find it fascinating. In this blog post, we will recap the past, which some of the time creeps its way back to Epec, the present, and the future of printed circuit boards (PCBs).
Let’s get to it.
Printed circuit boards (PCBs) require holes to be drilled through or partially through laminate materials. These holes are used to create continuity between the top and bottom or to a mid-layer on the PCB. The holes allow traces, pads, and copper polygons to be connected throughout the different layers of the board.
As our world continues to evolve to an online buying market for everything for our homes, schools, and offices, you may have noticed in some cases, the quality is not exactly what you thought you saw and bought online. We have all had that men’s XL shirt we bought for dad’s birthday arrive only to fit our 7-10-year-old, or the gift for Christmas arriving in January. Is it cost vs. quality, convenience vs. going out shopping, or is it the ongoing COVID-19 situation?
Within the first few pages of IPC standard for printed circuit boards, there is a reference table 1-2 that is called “Default Requirements.” When reading the standard looking for some guidance, one may question “default” as part of a requirement. Often, when we receive circuit board production files there is not enough information from a manufacturing standpoint but certainly enough to quote.
Remembering back to grammar school and the standard 8-box of Crayola crayons and when they expanded to 16 or 32 colors, never mind 64. If you managed to get this box with the sharpener, you had it made. I love color; the more the better.
