ESA Approves VT-901 in ACB Belgium's HDI Rigid PCB qualification image

We are pleased to announce that our VT-901 polyimide material is now fully and exclusively qualified by ESA in ACB Belgium’s manufacture of High-Density Interconnect (HDI) Printed Circuit Boards. With this recently obtained ESA qualification, ACB is currently the only PCB manufacturer able to offer HDI technology within an ESA qualified domain.

Ventec's VT-901 polyimide material offers exceptional reliability performance, meeting the demanding requirements of ACB's HDI PCB manufacturing process that adheres to ESA standards. It has a high Td of 395°C, a Tg of 250°C, and a Low-Axis CTE of 50.

Ventec manufactures all VT-901 polyimide using custom treaters equipped with advanced filtration systems and 100% Automated Optical Inspection (AOI) to ensure strict FOD-control and adherence to the IPC4101E Appendix A inspection standards for materials for space applications. The same specialized equipment is utilized to manufacture thin-core laminates that are specifically designed for the most challenging space and aerospace printed circuit board applications. ACB's advanced PCB manufacturing plant in Dendermonde, Belgium, together with Ventec's AS9100 Rev D accreditation for their manufacturing and distribution facilities, establish both firms as leaders in the supply of space and aerospace electronics.

Joachim Verhegge, ACB Belgium's Plant Director, says: “Further to our already existing ESA approval for Ventec’s VT-901 polyimide material in our Sequential Rigid and Rigid-Flex applications, we are pleased to now receive our ESA HDI technology qualification. This latest approval further reaffirms our position as a top-tier PCB manufacturer for the next generation of space programs.”

Peter Coakley, Ventec Director of Sales EMEA, commented: “We have a long-standing technology partnership with ACB, and I'm happy to support them in further strengthening their position as a leading provider of aerospace-standard PCBs. Ventec VT-901 polyimide's thermal resilience and suitability for usage in high reliability rigid and flex rigid multi-layers in the demanding aerospace sector are demonstrated by the most recent ESA approval for HDI Rigid applications.”
