They're also RoHS and REACH compliant, ensuring products meet EU environmental standards.
Jyväskylä, a university town in central Finland, is home to Jyväskylä Precision Assemblies, a supplier that's out of this world—literally. Specializing in aerospace and defense PCBA, they're one of the few Finnish manufacturers with AS9100 certification, the gold standard for aviation, space, and defense. "Aerospace PCBA is a different beast," says Quality Manager Liisa Heinonen. "Parts must work in vacuum, withstand radiation, and meet strict weight limits. We once assembled a PCBA for a small satellite that weighed just 12 grams but included 47 components—each soldered by hand under a microscope."
Their services include conformal coating (to protect against moisture and corrosion in space) and X-ray inspection for BGA (Ball Grid Array) components, which are common in high-performance aerospace electronics. "We also do a lot of work for drones and UAVs," Heinonen adds. "A Finnish drone company recently hired us to build PCBA for a long-range surveillance drone that can fly for 12 hours. The PCBA had to be lightweight but powerful—we used 0201 components and a 4-layer PCB to hit their specs."
Lahti Electronics Group is a true veteran, founded in 1987 and still going strong. With facilities in Lahti and Kotka, they serve a dual client base: medical device companies and heavy industrial firms.

Their facility includes a dedicated high-voltage testing lab where PCBA undergo hipot (high potential) testing to ensure they can withstand voltage surges. They're also experts in DIP soldering, a necessity for the large through-hole capacitors and transformers common in power electronics. "We recently partnered with a Finnish solar company to build PCBA for their next-gen inverter," Lehtonen adds. "By optimizing the layout and using high-efficiency components, we helped them boost energy conversion by 2%—that might sound small, but for a 10MW solar farm, it adds up to 200,000 kWh per year."
Last but never least, Rovaniemi Tech Solutions brings a unique angle: they specialize in PCBA for extreme cold climates. Located in Rovaniemi, the "Official Hometown of Santa Claus," they've made a name for themselves by designing electronics that work in -40°C temperatures—critical for Arctic industries like mining, oil & gas, and polar research. "Most PCBA fail in the cold because components crack or batteries die," says Founder Jukka Niemi. "We test every board in our environmental chamber, subjecting it to -40°C for 72 hours straight. If it works there, it'll work anywhere."
Their ruggedized PCBA is used in everything from Arctic weather stations to snowmobile GPS units. "We even built PCBA for a Finnish research team's polar rover, which is now exploring Svalbard," Niemi laughs. "They told us the rover's electronics survived -52°C—beating our own specs!" With MIL-STD-810G certification (for environmental durability), they're proof that Finnish engineering thrives even in the harshest conditions.
