We are very pleased to announce the introduction of our new fast & competitively priced solution for DEFINED IMPEDANCE PCB’s.
Our DEFINED IMPEDANCE pool service is designed for PCB’s that require a specific impedance for specific tracks. There is an online calculator to help you to define the correct values for these tracks and gaps.
The service is designed around 50Ω characteristic and 90Ω differential impedance requirements and uses material with a guaranteed dielectric constant (εr).

Manufacturing tolerances are the amount of variation that is allowed in a measurement
or other characteristic of an object.
Ref: Collins English Dictionary
Tolerances are everywhere, they are applied to everything that is manufactured whether it is a simple screw, a mobile phone or a spacecraft, they are all affected by tolerances and PCB’s are no different.
Even our domestic electricity has a tolerance, for example in Europe it is approx. +/- 6%.
When you design a new product, you do so with a specific set of dimensions in mind, these are known as the nominal dimensions.
However, these must have a tolerance, no matter how small (or large) they must exist to allow for cost effective manufacture.
We should all know that the smaller (tighter) the tolerance the higher the cost of manufacture will be.
For industrial PCB production there are international standards for these tolerances. We produce all our boards according to the “IPC-A-600 Acceptability of Printed Boards” version F (http://www.ipc.org/TOC/IPC-A-600F.pdf) Class II (Industrial products).
Using the Eurocircuits Insight Technology platform together with Eurocircuits TV we have created a series of informative guides that help explain these manufacturing tolerances.
Our first guide in this series is:
Finished Hole Size Tolerances
The finished hole size on a PCB is affected by the following factors:
Type of Hole – Plated, Non-Plated or Via.
Nominal Hole Size vs available Drill Bit Sizes.
Drill Bit Size Tolerance.
Drill Bit Wear during use.
Hole Cleaning (Desmear).
The Plating Process and Copper Balance.
The Final Surface Finish of the PCB.

After Directing Imaging (DI) of copper layers, Direct Imaging of Soldermask redefines the boundaries for the soldering of SMD components.
Direct Imaging is the biggest technological advancement for the manufacturing of PCB’s in the last decade.
Since we introduced the Ledia Direct Imaging system (DI) for Soldermask exposure at Eurocircuits, we have been working hard to find its optimum registration capabilities.
As a result we can now offer improved registration capabilities for Soldermask and we are now able to reduce the minimum required clearances for DI compatible Soldermask as below:
MAR to 0.030mm…from 0.060mm MSM to 0.070mm…from 0.100mm MOC to 0.060mm…from 0.100mm
Due to the improved registration it is possible to have Soldermask between the pads of fine pitch components and this helps to protect against solder bridging as below.
Smaller Soldermask openings give designers another big advantage, as it allows for tracks to be routed closer to pads.
From a manufacturing point of view, using DI for Soldermask has many advantages. For example, we can switch from one job to another in a matter of minutes as there is no need for films which is a timely process as used on conventional exposure systems.
DI Soldermask demands a premium price from our supplier, however, Eurocircuits believe the benefits out-way this additional cost and does not charge extra for the use of DI Soldermask.
We want our customers to benefit from using DI Soldermask and we see it as a win-win for everyone.
Available colours for DI exposure, at present, are Green, Red, Black and Blue.
