A large majority of the .4mm routed pitch BGAs require HDI PCB. If your IC designer leaves enough space, the best location for a mechanical through via is within the center of the BGA. To meet BGA requirements, it is okay to break other PCB design rules. Within tight BGAs, all bets ...
How laminate properties impact the PCB design process IPC standards for PCBs — what are they, why do they matter? Characterization of Epoxy prepregs by DSC Simultaneous Rheology-Dielectric Measurements of Epoxy Curing Characterization of Printed Circuit Board Materials by DMA Complete the form to the...
Adjust layout to avoid any exposed board edges post breakoff. Step 8 - Final Design Review and Artwork Submission Complete design review with PCB designer’s checklist as signoff. Have your layout reviewed by an experienced PCB designer.
In the PCB (printed circuit board) industry, it is common to panelize several boards on the same panel for PCB fabrication and assembly. PCB panelization improves the utilization of the PCB laminate sheet and SMT (surface-mount technology) assembly efficiency....
board, but the cost of purchasing the board is very considerable, especially the board of some imported equipment. In fact, you might as well use an eraser to rub the gold finger several times to clean up the dirt on the gold finger, and then try the machine again, maybe the problem ...
For this process, you must heat the PCB to a high temperature to recover the metals present on the board. Thermal recovery will incinerate the FR-4 but retain the copper. You can use this method if you choose, but it will create harmful gases in the air like lead and dioxin. Chemical...
Up to now, electronics products involved in industries of Automotive, Military, Aerospace and Shipping or have to work in high-temperature and high-humidity environment possibly suffer from PCB (Printed Circuit Board) failure due to chemical environment, vibration, high temperature and high humidity,...
Castellated circuit boards facilitate the integration of different modules into one design and also ensure efficient board-to-board soldering
Motherboards are complex. Let’s break them down, component by component, and explain how they work. Choosing a gaming motherboardis a hugely important part of building a PC. What does a motherboard do?It’s the circuit board that connects all of your hardware to your processor, distribute...
You can not unwarp/straighten a PCB after the soldering operation.Thin 4 or 5 mil traces will break. Stiffeners must be installed prior to soldering to keep the board flat. It does not matter whether it is a large board with heavy components or a panel of tiny boards. Warped boards with...
