Doing prototyping work ? Then watch our video presentation on 4L PCB plus a paste stencil:

Prototyping PCB Do-It-Yourself SMT assembly

Since surface-mount technology (SMT) electronics components are getting more common, electronics enthusiasts need to know their options for prototyping PCB designs which have such elements. Especially the shoestring budget do-it-yourself (DIY) guys have been leveraging painful techniques such as hand-soldering or spreading the solder paste on each pad separately. We wanted to point out that your options also include the use a paste stencil, which can add surprisingly little to the PCB price. A steel solder paste stencil (laser defined or etched openings) lets you squeeze the tin paste onto every component pad simultaneously, which saves a lot of efforts and properly applied also makes the job better. As part of our service we will find the lowest cost solution fitting your component pitch.

 

LNAFIN Wireless Energy Transmission First Test

Wireless energy transmission (WET) has been gaining momentum lately. The Wireless Power Consortium is a standardization organization, which promotes wireless energy transmission techniques.In the last year 2012 this technology finally got some other use than toothbrush charging, when Nokia made it available as a wireless charger for its high-end Lumia 920 model.

Interested in wireless energy transmission ? Then watch our video presentation on youtube:

It is still prudent to say that WET remains a challenge, at least if the devices are not touching and if the power is higher than sub-1-Watt. In this video we take a little step towards that difficutl region. Our results include transmission distances in excess of 2.5 cm and powers around 1 Watt. Also some tweaking to the energy transmission path is suggested at the end of the video.

PCB and Other Issues to Start a New Year with!

Our printed circuit board and electronics products found their first customers in Finland in 2012, so the end of the year 2012 did not see many blog postings from us! This is gonna change, especially as these English pages have now been published.

Good PCB Customer Response to Start 2013

It is a great pleasure to report that we have happy customers. A direct quote (with customer permission) explains it best:

• “Today i get from Post office my PCB boards. They look absolute great!!
  There was no need of that text layer on top, but otherwise .. look
  fantastic, and already i wish to start soldering elements :-)
  Thanks again and for sure my future orders will be from your company !“

We have also delivered Laser paste stencils in 2012!

A framed paste stencil much like the one shown here has been delivered to our customer to start 2013. Pre-tensioned in a steel frame, the 0.12-mm steel paste stencil performs well when it is used in administering ROHS tin paste to dense PCB layouts (the picture is shown with customer permission).

 

We now accept Paypal! Paypal is the world’s biggest internet payment method. Customers can now pay for LNAFIN products with their credit cards (Visa, Mastecard) or by using their account at Paypal. Additional information on our payment methods can be viewed here.

 

Now we have (hopefully) made our circuit board products easier to access by adding two web-forms for customer PCB data and gerber files. Using these two request-for-quotation forms, PCB dimensions can be given in millimetres or in mils (thousandth part of an inch). Asking for an offer is of course free!

We are very happy to say that we were able to meet the hard requirements of a VTT business case this month.  Technical Research Centre of Finland is one of the largest research organizations in Europe. It has an annual budget of 278 M€ and ca. 2800 employees.

The European Microwave Association is an international non-profit association with a scientific, educational and technical purpose. Our CEO joined EuMA to complement his existing electrical engineering community memberships within IEEE.

Our first power supply customer project for year 2012 starts. We won this project on the merit of our broad prior electronics design experience. At the moment we cannot elaborate on this, but after successful completion we will publish selected results in year 2013.

A three page journal article about LNAFIN has been published in January 2012. This our first ever appearance in the Press. The article presents us, our background and our Products and Services (PCB, PCB design, and ASIC). Please see us at Teollisuuden Näytelehti issue 1-2/ 2012 (in Finnish).

LNAFIN WWW-site pages now have more information about our circuit oriented products like: printed circuit boards (PCB, a.k.a. a printed wiring board), PCB layout design service, electronics design, also including the design service for application specific integrated circuits (ASIC).
