Dear Fastek. For the Front panel board we are using multible ( 4 boards in one PCB. even thought the balance between the DEK printer and the placers still big 6 sec as a difference. But, may be this is a good idea for the main board? may be also it's

Hello PR, PumpPrint� technologies enable high throughput adhesive deposition using a screen printing platform. Careful selection of stencil material, and informed study of the design of apertures and other stencil features, enables a wide range of

Tony Although I agree in principle with Dean that 45 Degrees would be ideal, most of the squeegees I have worked with have been 60 Degrees to the stencil surface. This seems to work best with metal squeegees when printing HASL boards, because the sl

Rich, I use water soluble in a DEK Proflow unit. We can print faster (about 4 times faster), and the paste lasts much longer than it being exposed to air. In addition to this, the prints we have now are even better than with a squeegee. I havn't

Pressure printing systems Conventional stencil printing techniques have fundamental limitations as regards paste handling: The volume of paste available for printing is limited, so frequent replenishment is necessary Paste is difficult to c

There are concretions that form inside the chamber when using a water soluble paste. They start forming and affecting print as early as 2 days. This is apparent no matter what type of print head you may be using. There has been over 30 water soluble

Hello Sami, if your placer is faster than your printer you must have very few components on the board, how many are there? What is the tact time of your mounter for this board, what is the tact time of your printer? How large is the board, can you s

We just started using DEK's pump print process on a high volume SMT line. We are using Hereaus 955. It works well for most components, but we have an issue with missing/partial glue dots on large diameter deposits (0.050"). The stencil will be com
