SMD assembling in clean room or White room

PROMAX is a registered ISO-9001: 2000 company. We offer to our clients the design, manufacture and also the test of printed circuit boards. We develope your projects with CAD/CAM design technology, assembly of SMD electronic components down to 0201 " and exhaustive optical and in-circuit tests that warrant the highest posible quality of production.

There is a continuous evolution towards integration of smaller components such as BGAs, fine-pitch, 0201 … In these cases a simple speck of dust in a weld can cause a defective printed circuit board. In order to avoid these risks, it is a must to produce in a clean room under controlled pressure, temperature and humidity conditions and with strict norms to warrant the cleanness of the environment.

• Conductive soil to avoid sparks.
• Production according to EU 2002/95.
• The personnel must dress special clothes and conductive shoes.
• Automatic control of temperature, humidity and particles in suspension.
• Pressurized air to guarantee the isolation from external air.
• 9 independent control stages oven that diminishes the thermal stress of the components.
• Optical printed circuit board and electronic in-circuit test.
• Computer controlled stock of components.
• The components are stored in an automated closet within the clean room.
