I think the Technitrol's wide range of products from electrical contacts to electronics and telecoms components can suit Vietnamese market. From this year Foxconn (
http://www.foxconn.com/PullulateCourse.html) starts to invest 5 G$ in Vietnam, this implies VN market contains not only retail but also wholesale demands.
To enter Vietnam market, Technitrol should find some giant distributor in Vietnam, it can help building brand name for your products in Vietnam. At this moment, to be appeal to those giant distributors, Technitrol can raise awareness in the electrical/electronics engineering community. The giant distributors in Vietnam often have research units and they are much influenced by their engineers.
For a preliminary investigation, you can place advertisements on several Vietnamese electrical/electronics community forums (like dientuvietnam.net, diendandientu.com), while giving sample products and technical support to those communities. Several small and big companies around those forums will contact you soon.
bxngoc can also be one to make bridge for Technitrol and Vietnam market, your reputation in this forum is now beneficial.
