Printed Circuit Boards

Our factory in Sweden can handle Quick Turn, prototypes and medium volume of Multilayer boards and single sided as well as double sided PCB´s.
Our coworkers long experience of PCB production makes it possible to offer flexible production and special solutions, such as aluminum boards, high frequency pcb´s, large antennas and heavy copper for power applications.

Our Printed Circuit Boards are used for all kind of applications – Robots for automation, sensors, IoT, communication, defence, aerospace, radar, medtech, telecom, automotive, ligthing, power grids and offshore.

Our latest investments in production equipment for direct exposure makes it possible to manufacture prototypes with tight tolerances, µBGA, fine-pitch and soldermask registration not possible until now.
Impedance controll and measurement of impedance are some of our skills. The feedback from production and technical department is instant, with optimized solutions for your design.

New drill machines and registration technology for drilling blind vias down to 0,15 mm in diameter, and new plating technology for small through vias are under development.

Special solutions

Our flexible production unit in Sweden offer many special solutions such as different soldermask colors , V – cut, depth controlled routing, heavy copper or peelable mask. We can also offer material without copper for insulation, panels and fixtures.

MMAB assists our customer during the development process.
Our own production in Sweden makes it possible to experiment and find new solutions. Isolated backing, special LED soldermask, thick nickel coating, autocatalytic silver, gold for bonding or durable rodium coatings are some examples of special solutions that makes MMAB unique. We have long experience of thin and large base materials and heavy copper multilayer boards for power electronics.

Volume production, HDI, 
Flex boards

Our partners in China can supply both small as well as large volumes of 1-32 layers in FR-4 and most kind of base materials for high temperature or high frequency.
We can also offer HDI boards with microvias, HDI, plug and plate vias for via in pad, high frequency material, Flex and Flex-Rigid.

In other words, all types of Printed Circuit Boards.

Metal base & LED

MMAB are a development partner for thermal conductive PCB ́s, such as aluminum substrates IMS (Insulated Metal Substrate) and other base materials for LED lighting. This have given us an advantage on the market for cost efficient manufacturing of metal base boards in our Swedish factory.

Read more about Metal base & LED

Metal base boards is used for applications where large amounts of heat must be dissipated, for example high intensive LED or high current products such as power supplies, frequency controllers or servo controlles. Metal base boards are normally using aluminum base on which a single layer conductive plane is separated by a ceramic insulation layer with high thermal conductivity. The conductive copper layer can be anything from 12 μm to 210 μm.

For LED – lighting with lower heat dissipation requirements there are other alternative materials in FR – 4 and thermal conductive CEM – 3. We have also experience of white soldermasks providing even light reflection with repetable color temperature even after soldering processes.

High Frequency base materials
& Antennas

MMAB can offer base material for low loss and low as well as stable dielectric constant. Unique for MMAB is our manufacturing of very large FR – 4 antennas and conductive patterns for radomes.

Isola, Rogers, Shengyi, ITEQ, just to mention some manufacturers, can offer base material with FR – 4 properties for more stable processing, thermoset material with and without ceramic fillers, and PTFE – material for Microwave.
MMAB will guide you in material selection, as well as in the possibilities with regular FR – 4. Rogers RO4350, 4725, 4730, 4830 and Isola FR408, Astra MT77 are some materials we can keep in stock for Quick Turn delivery.
We manufacture high frequency boards as single sided, double sided and multilayer designs with special low loss bond sheet or mixed dielectric with FR – 4. Our production resources within high frequency and high speed digital boards are silver plating, step plating and impedance measurement.

Unique for our production in Malmö, Sweden, are manufacturing of antennas up to 3000 mm in length and antenna segments in 0,1 mm material thickness.

RF & Antennas

We have extensive experience and knowledge in manufacturing of PCB antennas and printed circuit boards for radomes. Our production equipment at our factory in Sweden is unique and we are able to manufacture antennas and printed circuit boards for radomes up to 3000 mm in length on rigid or flexible laminates.
