As consumer devices continue to shrink in size, power considerations and appropriate thermal design become increasingly important for circuit designers and board layout engineers. This tutorial helps designers to ensure that a board is both electrically sound and thermally balanced for proper operation and optimum efficiency.

PCB terminal blocks series MVS15x-IT from Euroclamp provide an added value in the form of an easy connection of wire leads even in tight conditions. Thanks to a construction slanted in 35°, they fit exactly into conditions, where horizontal, neither vertical terminal blocks aren´t the right solution.
A relatively common situation – a construction of your device doesn´t allow you to use vertical terminal blocks and at horizontal ones you face the problem with components placed too close to a terminal block, thus preventing a proper installation of wire leads.
MVS15x-IT series slanted in 35° is the solution for such and many other cases. Available are versions with 5mm as well as 10mm pin spacing. Types with a 5mm pitch can be found in our standard stock offer. Basic components are 2 and 3-pole terminal blocks MVS152-5-IT and MVS153-5-IT. Also available is the MVS1510-5-IT, representing a price convenient alternative, when you need to create a row with 10 and more poles. Terminal blocks are made from PA (polyamide) UL94-V0 class, nickel-plated copper alloy and the screw is from a galvanized steel. Detailed information will provide you datasheets at respective types.

Automotive relay for PCB used by leading car companies was introduced to you in a recent article. Moreover, now you can buy this relay for a substantially lower price.
Relay V23084-C2001-A303, marked also as 1393267-2 is a well-proven 12V miniature double relay with changeover contacts, which can be used for servicing as well as for new applications. During past months we registered your stable interest about this type of relay, that´s why we tried to negotiate even better purchase conditions.
Advantages / Features:
- enclosed double mini PCB relay with CO contacts
- contacts from silver and nickel
- continuous current 20/20A
- easy PCB routing thanks to an optimized terminals layout
- convenient price
- specified temperature range -40 to +85°C
- coil 12V/ 255 Ohms
- dimensions 17.5×16.8×13.2 mm (LxWxH)
We managed it and we want to pass this benefit to you. This enables us to offer the relay to you for a considerably lower price than so far. Detailed information will provide you our article “Automotive relay for PCB used by leading world producers” as well as the V23084-C2001-A303 datasheet. A lower price is valid till actual stock sell-out.

Ever wonder how some designs group all the power supply pins in one corner of the schematic? They look organized, and it’s easier to understand how the circuit works because pins are grouped by function. In this tutorial we’ll show you how to make an Eagle part with separate power pins. This can be extended to group pins by function as well.

Most chips have multiple power pins that need to be connected to the same power supply, but Eagle doesn’t allow you to give 2 different pins the same name. This short tutorial shows how to get around this and name multiple part pins the same thing.

If you start tinkering with electronics, eventually you will want to make your own printed circuit board. In the olden days you could just buy an etching kit at your local radio shack. Now, most electronic projects are much more complex, the boards are much smaller, and you need to deal with 2 layers, surface mount components and vias. Rather than being just another PCB tutorial, this extensive two part overview covers the myriad of problems you may encounter and the methods available for solving these problems.
PCB terminal blocks Wago 233 provide a fast and reliable connection at production and also a very convenient way of installing for end users of your devices.
Perhaps the biggest advantage of Wago 233 terminal blocks is saving of space and a simple installation of wire leads. Pin spacing is only 2.5 mm and a simple pushing of a plastic lever is all that is necessary to insert of a lead.
This way of installation is very simple and intuitive. That´s why the Wago terminal blocks are very suitable even for products, where a user himself must connect leads, for example various security devices, controlling units etc. Usable are leads with a 0,08-0,5 mm2 cross section. Recently we enhanced our stock with next types, that´s why you can now choose from 5 types – 2, 3, 4, 5 a 12-pole. Upon order, we´re able to deliver you even other versions and also models in an orange color (with 2.54 mm pin spacing). Detailed information will provide you the Wago 233-203 datasheet.

Whether you’re a first-time circuit board designer or you’ve been doing it for years, you know how difficult it can be to visualize layout, spacing, and relative size in PCB layout software. You might have also experienced that uneasy “I hope everything is right” feeling when you submit your design files for manufacturing. You’re not alone! I’ve ordered boards with silkscreen text way too small to read, components on the wrong side of the board, and even had my silkscreen and soldermask layers reversed by mistake! Each of these times, the real problem was not having a good view of the design.
I came up with a solution to these problems and designed (with the help of a web developer) an online 3D Gerber viewer that anyone can use. If you’re not familiar with Gerber files, they are the files that layout software (like Eagle, Altium, etc) export for manufacturing. They describe everything pertinent about your board that will be required to actually create your PCB.

Some PCB fab houses (like SeeedStudio, with their Fusion PCB service) will allow you to panelize smaller PCBs. For example, if you have a 2.5cm x 5cm board, you could panelize two of them on to a single 5mm x 5mm PCB. Or, put a 7cm x 7cm board and a bunch of 3cm x 3cm boards onto a 10cm x 10cm panel. Seeed will allow up to 5 sub-boards on a panel.
The freeware and light versions of Cadsoft Eagle limit the design area of the PCB to 10cm x 8cm. This is enough to do many projects, but when you want to try and panelize to fill a 10cm x 10 cm board, it won’t work. Plus, maintaining separate projects and updating them on the panel, and maintaining consistency of labels and reference designators can be a pain.
