Introduction – LaserTec
Lasertec is a stencil manufacturing company in the industry since more then 16 years. Established in 1994, LaserTec is the leading supplier of precision SMT stencils and tooling products. Our ability to understand our customers needs combined with significant investment in state of the art Laser, CNC and CAD/CAM technology makes LaserTec the supplier of choice for the majority of electronics assembly companies. LaserTec is unique in the industry by providing its customers with a comprehensive range of products from laser-cut stencils, squeegee blades and holders, precision pallets and tooling products to high resolution inspection templates. All these products are produced from the same data source supplying our customers with the most effective and innovative solutions for SMT, Solderwave, Pressfit, assembly and other speciality applications.
All our products are designed to accelerate your SMT & assembly process, driving down production costs and creating a streamlined operation. See how a partnership with LaserTec can reduce your costs and help optimise the entire production process .
“ We guarantee Quality SMT Print Stencils Designed , manufactured and delivered on time every time“
LaserTec Solderpaste Stencils
LaserTec's expert Stencil Design team coupled with our unique precision stencil manufacturing techniques plays a key role in ensuring an optimum Stencil Printing Process . Control of the aperture characteristics, stencil thickness and accurate fiducial generation are directly related to the volume, alignment and positioning of paste deposited during printing. Correct stencil design, coupled with quality manufacture, makes a significant contribution to end of line yield.
LaserTec offer unrivalled turnaround times of 2 days as standard with the option of faster turnaround (4 hours) where required and no compromise in the accuracy and quality of the stencil . All LaserTec stencils are designed and produced to the highest standards. Our professional and skilled team are committed to working closely with our customers in order to develop optimum stencil/process specifications and advice is readily provided on all aspects of the screen printing process .
The cross section of a 16 mil pitch aperture cut by Laser illustrates the consistent cut quality and straight trapezoidal side walls which encourage optimum paste release. Guaranteed tolerance of aperture dimensions to ±5µm over the entire printable area of the stencil makes for consistent and accurate replication of board features, even with very large backplanes
Stencils are generated from stainless steel, carefully selected for flatness and uniform thickness - important qualities in a precision stencil.
LaserTec's expertise also lies at the heart of our precision stencil cutting equipment, featuring pumped Nd-YAG lasers. Our close involvement with the laser manufacturer ensures the highest levels of accuracy, repeatability and throughput; the foundation of a truly world class stencil service. LaserTec ensures100% inspection of every stencil produced using a high precision scanner as part of our final QA inspection.

Stencil Ordering Checklist
Frame / Foil Type:
Please specify the machine type and frame / foil size, or use our frame and foil codes (see “Customer frame codes.doc”).
If you wish to return frames to be re-used, please ensure they are clearly marked with your company name. Frames should be returned at least one week prior to ordering stencils. If we do not receive your frames in time for them to be refurbished we will supply your order with new frames and hold your returned frames in sock for future orders.
Squeegee Side:
It is very important that the correct view side of your data is clearly marked. If your data contains tracking and silkscreen layers we can normally determine the correct view, however if this data is unavailable please ensure you supply a plot of the image marked to indicate the squeegee side.
Fiducial Marks:
If you require fiducial marks please ensure these are present on your data, and indicate on the order form which side of the stencil they should be ½ etched onto. If the fiducial contained in the data are not of the correct size and shape please specify the required changes.
Aperture Modifications:
Please supply full details of any aperture modifications required. If you would prefer us to recommend modifications please indicate this on your order, and we will contact you to confirm suitable modifications.Please also highlight any items on the paste data that are not required as apertures on the stencil If no modifications are specified we will manufacture the stencil at data size.
Image Position:
Please indicate if you require the image to be placed centrally within the stencil, or if an offset position is required.
For offset images please supply a drawing showing the required offsets and the front edge of the image (note that it is essential that your data contains the full PCB / panel outline).
Data:
The paste data should ideally be supplied in extended gerber format (RS 274X), if possible please include layers for the copper tracking, silkscreen and PCB outline.
If your PCB is panellised or step and repeated please ensure that the data contains this information.
All files should be zipped together and attached to an e-mail giving full contact details (If your data is to be supplied by a third party please ensure they indicate that the data is being sent on your behalf).
To ensure rapid processing of your order please send both the order form and data together attached to one e-mail.
