about our company

LETEL elektronik s.r.o.

LETEL elektronik s.r.o. was founded in 1992 and it is dedicated to custom production and development of electronics. It focuses primarily on services in the field of production preparation, development activities, the actual production, and inspections of electronic devices, especially specialized devices such as sensors, security devices, etc. It performs custom mounting, soldering and testing of printed circuit boards.

Due to small to sample series, we provide these services mainly from the supplied material, but we are able to handle the order completely, including the design of the printed circuit board.

Since 1992, the company has been gradually growing and at the same time our technological equipment has been growing as well so that we can satisfy almost all requirements of our customers in the field of PCB mounting.

Thanks to the size of the company and long-term experience with German partners, we are able to respond to customer requirements flexibly, efficiently, and at affordable prices, including express delivery dates.


In the pre-production phase, it is possible to eliminate the possibility of future risks during the serial production.


Flexible and cost effective top quality custom production.


Implementation of development projects of PCBs, electronic devices, and their parts


Quality of our products and satisfaction of our customers without any compromise. We have been working according to the ISO system of standards since 1998. All products manufactured by our company are subject to 100% quality control. Most products are inspected by automated optical inspection AOI.

Our customers can be sure that their products will be produced in time, in high quality and at the agreed price. Quality and maximum customer satisfaction are our primary goals – quality policy.

High quality is guaranteed not only by our experienced team of employees, but also by a certificate of the quality management system ČSN EN ISO 2001: 2016, which is regularly confirmed by control audits.
