S-1688 Pneumatic Stencil Cleaner

Truly Automatic

For cleaning various stencils and misprinted PCBs, the combination of features offered by our S-1688 make it a unique, truly automatic cleaner. The threshold for usefulness of automation is allowing the operator to walk away from the process without worry. Stencil cleaners that require manual positioning and movement of stencils require attention from experienced operators to ensure consistent cleaning.

Economic and Environmental

No-rinse, aqueous cleaning agents for 100% closed loop process, for conformity to present and future economic and environmental operating requirements.The operator can start the cycle and walk away from the cleaning operation. Also, its compact footprint, integrated castors, and trivial connection requirements-its only connection is to a 240 volt outlet, with no water or drainage requirements-make it very flexible.

Frees the Operator

S-1688 frees the operator by combining a specifically shaped ultrasonic cleaning chamber, continuous filtering of the cleaning bath, automatic indication of liquid level and filter status, and an automatic loading/unloading of the stencil. Its integrated loading arm ensures that every stencil is position precisely the same way in the cleaning tank, and that it is withdrawn from the cleaning chemistry as soon as the cycle is finished. Its filtration system continuously removes soils from the cleaning liquid, often maintaining the cleaning effectiveness of the medium for a year or longer (depending on usage, of course)

How does SMT electronics assembly work?

Electronics manufacturing using surface-mount technology (SMT) simply means that electronic components are assembled with automated machines that place components on the surface of a board (printed circuit board, PCB).


Electronics manufacturing using surface-mount technology (SMT) simply means that electronic components are assembled with automated machines that place components on the surface of a board (printed circuit board, PCB). In contrast to conventional through-hole technology (THT) processes, SMT components are placed directly on the surface of a PCB instead of being soldered to a wire lead. When it comes to electronic assembly, SMT is the most frequently used process in the industry.

Electronic assembly encompasses not only placing and soldering components to the PCB, but also the following production steps:

  • Applying soldering paste, which is made of tin particles and flux, to the PCB
  • Placing SMT components to the soldering paste on the PCB
  • Soldering the boards with a reflow process.

Applying Soldering Paste

Applying soldering paste is one of the first steps in the SMT assembly process. Soldering paste is “printed” on the boards using the silk-screen method. Depending on the design of the board, different stainless-steel stencils for “printing” the paste onto the board and various product-specific pastes are used. Using a laser cut stainless-steel stencil custom made for the project, the soldering paste to be applied only to the areas where components will be soldered. After the soldering paste is on the boards, a 2D-soldering paste inspection is performed to ensure that the paste is evenly and correctly applied. Once the accuracy of the soldering paste application has been confirmed, the boards are transferred to the SMT assembly line, where the components will be soldered.

Component  Placement and Assembly

The electronic components to be assembled come in trays or reels, which are then loaded into the SMT machine. During the loading process, intelligent software systems ensure that components are not inadvertently switched or misloaded. The SMT assembly machine then automatically removes each component with a vacuum pipette from its tray or reel and places it on its correct position on the board using precise pre-programmed X-Y coordinates. Our machines are capable of assembling up to 25,000 components per hour. After the SMT assembly is completed, the boards are moved on to the Reflow ovens for soldering, which affixes the components to the board.

Component Soldering

To solder electronic components, we use two different methods, each of which has distinct advantages depending on the order quantity. For series production orders, the Reflow-soldering process is used. During this process, boards are put in a nitrogen atmosphere and are gradually warmed up with heated air until the soldering paste melts and the flux vaporizes, which fuses the components to the PCB. After this stage, the boards are cooled off. As the tin in the soldering paste hardens, the components become permanently affixed to the board and the SMT assembly process is completed.

For prototypes or highly sensitive components, we have a specialized vapor-phase soldering process. In this process, boards are heated until the specific melting point (Galden) of the soldering paste is reached. This allows us to solder at lower temperatures or solder different SMT components at different temperatures depending on their individual soldering temperature profiles.


AOI and Visual Check

Soldering is the second-to-last step of the SMT assembly process. In order to ensure the quality of the assembled boards, or to catch and correct a mistake, AOI visual inspections are performed for almost all series production orders. Using several cameras, the AOI system automatically checks each board and compares the appearance of each board with the correct, pre-defined reference image. If there are any deviations, the operator of the machine is informed of the potential problem, who then corrects the mistake or pulls the board from the machine for further inspection. The AOI visual check ensures consistency and accuracy in the SMT assembly production process.
