SMT-PCB-A4 Manual Stencil Printer Operation Manual

1) Overview
Thank you for purchasing the SMT-PCB-A4 Manual Stencil Printer.
The field of application of the SMT-PCB-A4 is the (double-sided) SMD PCB assembly of
prototypes and small series.
The SMT-PCB-A4 has been designed to coat PCB's with often free of charge frameless stencils
with solder paste without major compromises on the print quality and reproducibility of professional
stencil printers.
The SMT-PCB-A4 is characterized by the fact that the stencil is largely stress-free on the PCB and
the two PCB holders rests. This eliminates the need to to clamp stencil, whereby the set-up time
also compared to professional stencil printing is significantly reduced, especially for small
quantities.
The SMT-PCB-A4 contains no moving parts and is therefore pronounced by design precise.
This guide describes Stencil printer, the commissioning and the use of of the SMT-PCB-A4
The operation of the SMT-PCB-A4 is very easy. Nevertheless we ask you, to the read the manual
completely before using it for the first time and especially to read the notes.
If you have questions, criticism or suggestions, please do not hesitate to send an email to
info@ khs-instruments.
Following some unavoidable legal advice:
The stencil printer may only be used for its intended purpose (see following Paragraph). All other
applications are not allowed and lead to the void of all liability.
Please read this manual carefully and completely before using it for the first time to avoid
damaging the stencil printer, the material, persons and the environment.
Failure to follow or obey the instructions in this manual will invalidate the instructions liability of the
manufacturer.
Dr. Schmidt Messtechnik reserves the right to make changes without notice and make
improvements to existing products.
Note: The SMT-PCB-A4 has no CE mark because it is not under the Machinery Directive falls. In
the EU a CE marking without legal basis is inadmissible.SMT-PCB-A4 instruction manual

2) Intended u e
The stencil printer TM-SP-A4 (called product below) is used for coating of printed circuit
boards with solder paste. All other applications and applications are not allowed.
The product may only be used if the operating instructions and all relevant provisions have
been fully read or taken note of.
Before use, the product must be inspected for possible damage, such as missing or loose
parts. In this case, the product must not be used.
The product must be transported with care, because if it falls down body parts can be
injured or the product can be damaged.
In particular, make sure that there are no loose parts on or on the product that could fall off.
The product may only be used and maintained by adequately trained and adequately
qualified personnel.
The product may only be used on a level and non-slip surface.
The product may only be used with solder pastes which comply with the legal
requirements.
When operating the product, all current accident prevention regulations must be observed.
The product must be kept away from children for health hazards and possible ingestion of
small parts.
Particularly important:
- The stencil must be checked for sufficient elasticity before use in the product.
- The safety instructions of the solder paste manufacturer must be observed.
- Take care the stencil may have sharp edges: Ri k of injury
