Definition of Tolerance for Manufacturing 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 […]
Eurocircuits Introduces – PCB Prototype 3+3 Service Eurocircuits understands that Time-to-Market is crucial for developers as they need to meet shorter lead-times to maximise the potential of their new products. Since the beginning of 2019 we have developed and introduced new software, manufacturing processes and equipment that allows us to reduce the manufacturing and […]
What tolerances should I design into my PCB? Where possible design your PCB to meet industry standard mid-range tolerances. Eurocircuits use these specifications and tolerances as the basis of our lowest-cost pooling services. For more detailed information on our Manufacturing Tolerances please see our Tolerances on a PCB page.
Eurocircuits uses cross sections as part of its quality control Cross sections are a power tool that ensures high quality production and products. Preparation of a cross section is a destructive process, a section of the production panel is cut out, in most cases a specially designed Test coupon is used (these are placed on […]
Standard and Predefined Build-ups A few months ago, prepreg construction 2125 was removed from the available prepreg list of 370HR and IS400, 2 of our main FR4 material types. We exchanged this prepreg type with construction 2116. The thickness of 2116 differs from the 2125 with approximately 20 µm. At first we assumed it wouldn’t […]

Hand-soldering with the same high quality result as reflow or wave soldering? Are you ready for the challenge ? Let us look at the mini-wave soldering technique. This picture shows that tools and skills are the basics to achieve a good result in hand-soldering. You agree ? Hand-soldering is in most cases the last step […]
