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.

Have you ever needed to build a prototype PCB at the last minute, the first one failed but you’ve identified the problem and with a small manual modification to the circuit on your spare PCB you could prove it works!
The problem is soldering the components to the PCB, you could send it out but that would take time and as time-to-market is critical it’s would be faster and easier to do it in-house, but how?
Eurocircuits are all too aware of this problem and that’s why we developed our range of compact Benchtop PCB Assembly equipment, designed to give you the flexibility when you most need it, at that critical point in your development process.
The range of eC-equipment developed by Eurocircuits allows you to take a bare board and assemble it easily in house, there is even a hand held functional tester available, the eC-test-mate.
We have launched a promotion for our best seller the eC-reflow-mate oven.
The eC-reflow-mate oven gives an even temperature across the board with full user control throughout the soldering process.
It is controlled by the eC-reflow-pilot software which allows the user to define and store an unlimited number of temperature and time profiles, it also allows for the monitoring of the exact process for each board.
Separate sensors can be used to measure and display the temperature profile on the actual board.
It is a great solution for your in-house benchtop assembly requirements.
Order the eC-reflow-mate now and combine it with any additional eC-equipment and receive a 10% Discount on these items. This discount will also apply to any other Off the shelf items (we have a range of accessories and consumables available) that are checked out at the same time (as in one order).
Below is the full range of our eC-equipment, just click on the links to find out more.
