LNAFIN Oy Participates in Alihankinta 2016 Trade Fair

Alihankinta 2016 is the foremost international industry trade fair in Finland. Industrial subcontractors have been gathering to Tampere for years to gain visibility, new business contacts and new ideas. The Alihankinta fair is held annually in Tampere Exhibition and Sports Centre, Ilmailunkatu 20, 33900 Tampere, Finland. This year’s fair has attracted 1000 exhibitors from 20 countries. As a result of that, the exhibited products and services vary tremendously. However, Alihankinta Fair main product categories have been categorized as: production methods, products and components, R&D and design services plus ICT. Thus we feel that LNAFIN Oy PCB layout design, PCB deliveries, electronics assembly, R&D services, wirebonding, prototyping and RF design know-how has something to offer for Alihankinta 2016 visitors.


Visit LNAFIN at C430 and Win!

You will meet us in C-hall at our booth C430. We are very satisfied to have gotten a booth in this year’s outsold event. At the same time we wish that many fair goers would have an interest in electronics products and design services. We would be pleased to discuss circuit design and printed circuit board related prototyping/production needs. All booth visitors can take part in our small fair lottery. We will randomly draw winners to receive gift certificates for our products. Winners will be personally informed. We have included two maps of the area in this post: the blue map above shows the general exhibition area layout, whereas the black-and-white map below shows the C-hall exhibitor map.LNAFIN Oy Alihankinta 2016 C430 map

LNAFIN Oy Trademark (TM) Registered

LNAFIN Oy registered TrademarkLNAFIN Oy Trademark Registration Celebrates Exports to 6 Countries Worldwide

To celebrate our starting sixth year in business, we have registered our trademark (TM) at the Finnish Patents and Trademark office. Our trademark LNAFIN cube logo is shown here with the famous circled R-letter. Its basic idea is to combine words LNA and FIN in a graphic form. LNA stands for Low-Noise Amplifier, which is a key block in most radio systems. We have one US patent on LNA structures. As for FIN: that stands for Finland. LNAFIN Oy operates from Helsinki, Finland, and we also wanted to give credit to great Finnish RF and electronics engineers.

Growing customer base has been one of the key reasons for TM regisration. This Spring our export destination count reached 6 different countries such as: USA, Russia, Denmark, Great Britain etc. We appreciate our customers’ trust very much and we will live up to it in the future too. We have delivered various printed circuit board related products such as PCB design, PCB sales and electronics assembly services.

Sprint Layout files for PCB production!

LNAFIN Oy now Adds Sprint 6.0 Files for accepted PCB Production Data

Sprint Layout acceptedSprint PCB layout design program is useful for the printed circuit designer who wants to layout designs directly without schematic entry or any such complexities. This simple productive tool offers professional PCB layout capabilities such as design reuse etc. and is thus very popular both in professional and hobbyist circles. In recognition of that, LNAFIN Oy has decided to start accepting native sprint files for PCB deliveries. These can also be used for prototype and series PCB assembly services when good Bill-of-Materials (BOM) is also included in the zip-file.

Several PCB Layout Programs Supported

LNAFIN Oy has long supported several PCB layout programs such as: Mentorgraphics PADS, Eagle, and KiCAD. PCB layout design services are also available using these tools as based on customer schematic files. The Sprint data format complements our previously supported express-PCB PCB production in the sense that both tools focus on layout-only PCB approach. Here’s the Sprint quick logo for those who recognize that better:

New Address

We have relocated to bigger office space in Helsinki Hermanni area. The place is conveniently located as it lies at a 3 km distance from both the Helsinki Main and the Pasila Railway stations. Moreover, the drive  to the Helsinki-Vantaa International Airport takes only 19 minutes.
New address: Orioninkatu 4, 00550 Helsinki, Finland.
Please note that the PO.Box 28 address we previously had for mail has been closed!
All mail should be send to our office in Orioninkatu.

Prototyping PCB video

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.


Wireless Energy Test Video Published

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.
