PCB Assembly: What is Centroid Data?

2017-08-08

Shenzhen Grande Electronic requires centroid data to place the surface mount parts on circuit boards. Centroid data is the machine file in ASCII text format which comprise reference designator, X , Y , rotation, top or bottom side of the board.

Suggested 14 and 16 Layer PCB Layouts

2017-08-07

When the outer layers have GND and PWR stack ups, these boards should be used for short trace runs or fan outs only. The second layer is the signal layer for the purpose of HDI

Raw Material Choices for PCBs

2017-08-05

This chapter relates the best practices for choosing materials to manufacture multilayer PCBs that achieve two critical requirements: (1) limit manufacturing problems (e.g., bowing or twisting, as well as mis-registering; and (2) coming up to the standard

Plated Half Holes PCB

2017-08-04

Rows of holes are drilled alongside the boundaries of a PCB to produce plated half hole PCBs. When the holes have been through plated, the edges are pruned so the holes along the boundary are reduced in half. The edge of the PCB will look like the top of

PCB Multi-Layer Stack-Up

2017-08-03

Grande Electronics provides a PCB multi-layer stack-up services. PCB multi-layer stack-up defines the material thickness and copper weights needed to build a particular multi-layered PCB.

PCB Outline Layer And Keep-out Polygon Clearance

2017-08-01

PCB designers must be diligent about their outline layers and their keep-out clearance. Much thought must be put into this because many problems can arise from neglecting these details.

PCB Footprints and Soldermasks

2017-07-31

Electronic Design Automation (EDA) typically contains all PCB footprints for commonly used components and packages but sometimes the footprints are modified a little or in most cases their dimensions are a bit off.

NRE and Tooling Costs - What You Need to Know for Your PCB Project

2017-07-27

The NRE charge on your turnkey PCB assembly quote accounts for the cost of services such as the programming of Pick & Place, Reflow Soldering, and Inspection machines, as well as the creation of solder stencils and electrical test beds for your partic

PCB Assembly: The Benefits of Embedded Discrete Components

2017-07-26

The benefits of embedded PCB components is still a relatively new process, yet fabrication houses around the world are turning to this manufacturing process to eliminate problems such as parasitic effects and to reduce the PCB footprint, both of which are

The 10 Best PCB Design Solutions

2017-07-21

PCB design solutions are software tools that automate many of the tasks that EDEs previously performed manually over the course of designing an electronic circuit.
