Formatronic : PCB manufacturer - PCB - France

Manufacturing unit

All PCBs and stencils are manufactured at our factory in the province of Shenzhen, which employs 500 people and operates in three eight-hour shifts with a daily production capacity of 10,000 square meters.

UL approved, ISO certified and located in the largest PCB manufacturing area in the world, the plant offers a quick response due to its close relationships with suppliers (laminates, inks, chemicals).

The plant has its own stock of raw materials (KingBoard, Shengyi, HITEK, Rogers) as well as a permanent level of physical stock with our partners.

50 engineers take turns at analysing customer files and preparing production. An IT tool monitors production and provides customers with information about their orders.

2 production lines, one of which is completely dedicated to creating prototypes, maintain a triple focus on quality, price and timescale in accordance with standards in force.

Highly skilled employees combined with state-of-the-art equipment guarantee impeccable production quality, especially for printed circuits boards requiring particularly fine etching (0.075mm minimum insulation on 12 to 18µm copper and 0.1mm on 35µ copper) and for HDI PCBs (via laser, specific stacking).
