HERE - Densen

20Production technologyAll Densen products are manufactured using the most recenttechnology. Nearly all circuit boards are made of teflon, and aredouble-layered boards, so that you can have a noise screeninglayer on the one side. Many of the components we use, are of theSMD type (Surface Mounted Device).One of the advantages is that the SMD component lies directly onthe circuit board, so the soldering tin is almost only used to holdthe SMD component.On the conventional resistor there is no direct contact betweenthe circuit board and the feeder. This means that the electriccontact is not all that good. Furthermore, the signal must gothrough the feeder as well as the casing of the resistor to reach theresistor element, which is a bad solution compared to the directway of the SMD component.At the same time, the SMD components are mounted with anaccuracy of 0.02 mm! and the soldering is carried out in anartificial atmosphere of nitrogen to avoid oxydation of thesoldering. This, by the way, applies for all solderings in Densenproducts, including solderings on conventional products.Choice of componentsuse them, no matter what they cost.... Yes, no matter what theycost, since - due to our large-scale operations - we are able to buycomponents at prices that allows us to develop our productswithout economic considerations.An example could be the output transistors we use in the DM-10amplifier. The output transistors are also used in some of theworld’s most expensive high end amplifiers at more than 11 timesthe price of a DM-10, but then, also in a DM-10.Like many other components in a Densen unit, the capacitors inthe power supplies are custom-made for Densen. This is asolution we often have had to resort to as we simply cannot findcomponents good enough in any other way.We measure and select many components to ensure that thequality is high enough, and that the components match oneanother.This, for instance, is the case with the Alps potentiometers, wherewe discard 35 %. And this is the case for all transistors in ourproducts that are selected by robot before mounting.When we use standard components, these are also of the highestquality. This, for example, applies to the resistors in our products,all of which are 1% non-inductive metal film resistors, speciallydeveloped for demanding military use.We only use the positively best components in our products.Often you will hear certain types and makes mentioned as beingthe best. It is not certain that we use these, but you can be surethat we have tested them, and if they are good enough, we will
