Our production means
Our core business is in small and medium production runs, but our modern, high-performance means of production enable us to handle larger-scale production runs.
Electronic boards
In addition to a mastered manufacturing process adapted to both recent and older technologies, we offer a wide range of services associated with electronic board assembly.Boards can be assembled according to a RoHS or SnPb process, depending on customer requirements.
Other specific documentation requirements can be handled on request (IPA report, DVI,FMECA analysis, etc.). Complete manufacturing files are archived and can be consulted onsite.
Key strenghts
A flexible production tool (ability to switch from one production run to another quickly), staff trained in IPC A 610 class 3, IPC-7711 & 7721 repair, implementation of a manufacturing process adapted to the specific features of each board (use of Mycam software for manufacturing drawings).
Technologies mastered
BGA and QFN, direct Fet, SMD components, SMD installation, SMD small packages up to01005, through-hole components, high-density boards, rigid flex boards, wire bonding.
Related services
Spray varnishing (acrylic and silicone varnish), potting, gluing, mechanical assembly.
Testing and reliability
AOI inspection (systematic), 100% visual inspection (systematic), burn-in, mobile probe test, AOI inspection (systematic), functional test.
Prototyping
Since the end of 2023, as part of its strategy of supporting its customers and prospects, and with the support of its Lean Manufacturing approach, Seprolec has set up a complete process for prototyping requirements. In addition to board assembly, our aim is to support our customers in the industrialization of their products, right from the prototyping phase. Our services can therefore be accompanied by a DFx package (Design for Test - Assembly -Procurement - Cost, Automatic assembly...), through which our customers can control their design.
