We produce PCB with controlled impedance
We move with the times and therefore we introduce the production of PCB with controlled impedance. The development of electronics pushes impedance-controlled board technology forward, thus, it becomes the standard, and we keep with this trend.
Connections on impedance-controlled boards perform the function of a signal transmitter from one device to another, so the emphasis is on the board to be etched and compressed as accurately as possible. If it is manufactured to the required standards, the resulting product will work properly.
Typical areas of application are telecommunications, video signal processing, consumer electronics, automotive, aviation engineering, GPS, radar, color printers, computers, video games, DVDs, phones, etc.
The most common example of a signal transmission is a coaxial cable that transmits a signal from a home television antenna to TVs. When it does not meet the desired impedance, the picture on the TV is not of the required quality. Earlier analogue broadcasts were said to have „ghost“ images.
Similar examples can be found on most printed circuit boards in the form of single reference ground conductors, differential pairs, coplanar single conductors, or coplanar differential pairs.
In order to guarantee the integrity of the signal in these conductors, especially for fast switching of parts with a rise time of 1 to 2 ns, the impedance characteristics of the connected conductors must be observed. A tolerance of 5 to 10% can be guaranteed for these characteristics.
Customer tolerance requirements are checked with Orbotech-InStack software before the impedance-controlled board is manufactured. According to the results, the ideal composition of the multilayer board is chosen or corrections of the thickness of individual joints are made.
The final measurement is performed using a Zmetrix ST600 on a production coupon that is located in close proximity to the required PCB.
