DIMA Dispense Technology, a division of the DIMA Group and Dipaul Technologies are proud to announce the successful installation of a complete selective conformal coating line at Piramida in St. Petersburg in Russia.

Piramida is mainly focussed on the military industry and uses different types of coating material to protect the electronics they produce. Highest quality, flexibility, being able to supply a full line and the most progressive coating machine have been the key reasons for Piramida to choose DIMA as a partner to automate their coating production. Another main reason was the ability to use the famous Russia polyuretane material UR-231. 

Piramida was looking for a highly flexible selective conformal coating line. They have a wide variety of different boards to be coated and were looking for the possibility to use different types of coating material. Besides flexibility, high quality performance was an absolute necessity in order to guarantee the level of high quality products being produced. Another important selection criteria was the ability to receive local support for the line and the coating process, which is supported by Dipaul Technologies. During the selection criteria Piramida's technical engineers visited several companies to see all kind of coating machines in a production environment. The final decision to choose the DIMA coating line solution was based on the following aspects. The HC-200 has standard integrated process control by monitoring all available material and atomising air pressures to ensures repeatability and product quality. Furthermore the HC-200 has the ability to have a total amount of four different dispense and spray valves mounted in the machine. Also the possibility to use up to four different materials within one program. The solid mechanical construction and the best qualified software that enables full off-line preparation of boards was another major decision making argument. The standard integrated camera that can be used for fiducial alignment, but also for inspection was also beneficial compared to other suppliers. Finally the HC-200 is utilizing a 4 axis machine with rotating head that enables to dispense under any required angle with the dispense or spray valve pointed straight down or under an angle when the valves are being tilted. This Provides Piramida with a machine that can handle not only the boards they need to coat today, but also with the insurance that any new board that is being designed in the future can be coated on the DIMA HC-200.

OFF-LINE PROGRAMMING HYBRID COATING MACHINE

Being the first supplier of Conformal Coating systems with a standard integrated camera for fiducial alignment and process control, DIMA Dispense Technology has even taken the Hybrid Conformal Coating System to a next step. By releasing the latest version of Hybrid Coating software we have created the possibility to fully off-line program a coating process in the most optimal way.


 

The standard integrated camera of the HC-series coating and dispensing machines was already being used for fiducials alignment, inspection of the boards and easy programming of the machine. This prevented the operator to stick its head inside the machine in order to find the correct coating positions, or to see if the coating was applied in the correct areas. The camera could also be used to easy program the machine. 

At DIMA we belief that a machine should be used for production, not for programming. Therefore DIMA is again ahead of the industry by being the first supplier to enable true off-line programming. At DIMA it is not only a promise, it is the only one that really works!.

Off-line programming starts with taking a picture of the board to be coated. Us-ing the fiducial XY co-ordinates from a CAD-file enables to size the picture inside the software to its true size. After doing this programming becomes Childs play. Within the camera image shown in the software we indicate the size of the selected nozzle used to coat the board together with the selected width of where the coating material will be applied. (Picture 1, nozzle size (purple) and material width indication (black & white)) This makes it extremely easy to determine whether the selected nozzle would interfere with high components and furthermore you can exactly specify where the coating material will be applied on the board. When a line is being programmed this line is being drawn on top of the picture. This line that represents the coating material on the board is drawn transparent in order to still see which components are being covered and which are not. (Picture 2, transparant coating layers with 2 different colours) If different materials or different viscosities are being used, you can even specify this by using different colours. By indicating where the coating material will be applied, programming mistakes are also being limited. Furthermore it also helps to avoid that areas are being coated twice. Within each program you can select up to 4 different nozzles and 4 different materials. When choosing a different nozzle, automatically the nozzle indication in the camera image is being adjusted as well. All parameters to create a required line width and thickness are taken from a library within the soft-ware. All data per line created in the software can easily be changed in order to fine tune the coating program. Well known features within the electronics industry like creating a multiple board out of a single board, bad marking a panel within a multiple board and creating a variant are also available within the Hybrid Coater software. When creating a multiple from a single board provides the advantage that if something needs to be changed on the single panel, this change automatically is being transferred to all other panels of the multiple board. (picture 3, multiple boards) Like it should be, Dima is the first oneto provide the opportunity to coat boards on a coating machine while at the same time new boards can accurately be programmed off-line, without the need to use the machine and therefore having to stop the pro-duction. Again DIMA is leading the market and it is our goal to stay ahead of the market.
