What is PCB Test and Why Testing ?
Functional test (FCT) is used as a final manufacturing step. It provides a pass/fail determination on finished PCBs before they are shipped. An FCT’s purpose in manufacturing is to validate that product hardware is free of defects that could, otherwise, adversely affect the product’s correct fun...
Frontend Engineering Process Common Issues
Rule number 1 Do not scale your data - All data provided must be scale 1/1 (100 %). Rule number 2 Make sure that your Gerber files DO NOT contain apertures with a zero-size (size =0.00 mm or inches) and that your Excellon data DOES NOT have zero sized tools ( size=0.00mm or inches). Rule number ...
Tips for Electronics Project Designer
Good electronics project pcb board design references and tips can accelerate your practical know-how in electronics. Getting good and timely information on the electronic project that you are embarking on pcb board sometimes can be time consuming and frustrating. Hence, the objective of this site is...
Basic PCB Design Rules
These 28 Basic PCB design guidelines set out best practice to reduce the cost of your boards and to minimize the risk of errors arising during manufacture. High power boards have different rules especially in terms of spacing, traces size and power isolation. Manufacturers have different requirement...
PCB Design Equipment
In the early days of PCBs, the design and layout was undertaken manually using tape that was placed onto a translucent film. These PCB designs were normally four times the required size and they were photographically reduced onto a 1:1 film for the PCB production process.......
How to drill a PCB
Step 1: Planning / Materials This started when we realized pcb board we wanted a simple high-quality PCB drill dress, but didn't want to pay $400+ for something that would only run at around 20,000 rpm. We also did not want to use the standard dremel drill-press for drilling PCB's as they tend to br...
PCB Drill File Requirements
All PCB holes are plated through meaning, there will be solder in the PCB hole barrel. Must be Excellon format Must be ASCII text viewable. Please open with “Word” or “Notepad” to verify a numeric list of X & Y coordinates. There should be no strange graphical characters. PCB drill file sh...
Excellon Drill File
The drill file is also commonly referred to as an NC (numerically controlled) drill file in the industry. Excellon is the preferred term used with our Sunstone services. The Excellon drill file defines hole locations (X & Y coordinates) and tool numbers . Sunstone Circuits has removed drill size res...
How Do Motherboards Work
If you've ever taken the case off of a PCB computer, you've seen the one piece of equipment that ties everything together -- the motherboard. PCB A motherboard allows all the parts of your computer to receive power and communicate with one another. Motherboards have come a long way in the last twe...
What Do Modern Motherboards Include
Sockets (or slots) in which PCB one or more microprocessors may be installed. In the case of CPUs in BGA packages, such as the VIA C3, the CPU is directly soldered to the motherboard. Slots into which the system's main memory is to be installed (typically in the form PCB of DIMM modules containing ...
