TS PCB – towards the Industry 4.0

The enormous development of broadband Internet technology, of wireless communication, together with the increase in the computing power of computers and microsystems, which has been observed for over ten years, has created new opportunities in many areas of life. One of the results are the smart dev...

Industry 4.0

"Smart factory" is a slogan that has been appearing for a long time in foreign trade press. It is also being more and more often mentioned in the context of polish industry. Full automation of production seems to be the only right direction for the development, the fact that is slowly beco...

Standard structure, non-standard application of PCBs

With the use of typical elements, such as tracks and metallised holes, one can realize more complex technological solutions on the surface of a printed circuit.   The first atypical application of the printed circuit, which is worth mentioning, is the creation of integrated modules that a...

Unusual applications of printed circuit boards and laminates

A printed circuit board is most likely defined as copper track layout placed on both sides of the dielectric substrate, connected by appropriately located metallic through holes (Fig.1).   Fig. 1   Its essential features are especially durable and accurate representation of...

Solder masks in printed circuits - designing

Masks are prepared as negative layers so any components placed on them will in fact be areas free of paint. Typically these are SMD pads or assembling holes which can be defined in two ways (fig. 1): - by copper which means that the mask does not influence the pad size — the opening is larg...

Solder masks in printed circuits - performance specifications

The specification most often charactering the mask’s performance is it thickness.   In the case of a wet mask, it is a maximum of 40 µm ÷ 50 µm (thickness in mass areas) assuming that it is applied to copper with a typical thickness of 35 µm. The mask has a...

Solder masks in printed circuits - application process

The solder mask (wet) is applied to the surface of the circuits using two methods: screen printing and photo printing.   Screen printing consists in applying the mask image by means of a screen and then hardening it thermally or with use of UV radiation.   In the photo printi...

Solder masks in printed circuits - types and basic functions

Mosaics of printed circuits are made from copper whose major advantage is excellent conductivity of electrical current and heat. At the same time, this metal is susceptible to the adverse effects of oxidation when in contact with air and moisture. In order to protect mosaics from environmental impac...

Manufacturing printed circuit boards – now and then, part 2

Looking through the TS PCB TECHNO-SERVICE S.A. archives, we found a photo of a brushing machine we used in the 80.     Photo: brushing machine_archive TS PCB TECHNO-SERVICE S.A.     The machine we are currently using enables us to reduce the number...

Manufacturing printed circuit boards – now and then, part 1

Does anyone still remember AWS-1 NC driller?   When TS PCB TECHNO-SERVICE S.A. was initiating its production activity in 1985, it was a jewel among our machinery.     Photo: awS-1 NC drill_archives TS PCB Techno-Service S.A.   Now nothing reminds us...
