Precision motion engineering // semiconductor equipment

One team for the complete motion module.

MechanicsElectronicsMotion controlServo software

Machine builders need more than a motor and more than an advisory report. DSOTEC designs, builds, and validates the entire motion module, then transfers full production ownership to you. No seams between disciplines. No handover gap. No lasting dependency on us.

The engineering stack

Four disciplines. One contract. One team accountable.

A precision module fails at the boundaries: where mechanical tolerance meets a control loop, where a drive meets the software that commands it. DSOTEC owns every layer, so the tradeoff between performance and cost is made by one engineer who sees the whole axis/module, not five vendors optimising in isolation.

LAYER 01

Mechanical design and integration

Motor selection, linear guide rails and carriages, encoder integration, cable management, lubrication, tolerance stack up, and structural analysis for the full axis/module.

LAYER 02

System architecture and electronics

Top down axis or module definition before hardware is committed: single axis or coupled multi axis (MIMO) architecture, fieldbus choice (EtherCAT, PROFINET), safety strategy (STO, SS1, SOS), drive and controller selection, and current loop bandwidth analysis.

LAYER 03

Motion control and tuning

Hands on commissioning on ACS, ETEL, TwinCAT, Beckhoff or your platform. Current, velocity, and position loops, homing strategy, safety configuration, and fieldbus parameters.

LAYER 04

Servo software development

Motion application software to production standard in Structured Text, Function Block Diagram, or Python: trajectory generation, synchronisation, state machines, diagnostics, and automated validation.

LAYER 05

Dynamics and validation

The layer that ties the rest together. Frequency response modelling, move and settle simulation, cross axis coupling and MIMO decoupling analysis, resonance and thermal analysis, so tradeoffs are proven before anything is built.

What we solve

A module that needs designing, not assembling.

Some modules need a new design from a blank sheet. Others are already built, and need a redesign because the spec was never met or is outdated. A module is rarely one axis tuned in isolation and it's often several axes whose dynamics interact, and treating them as a coupled MIMO system is frequently the difference between hitting spec and chasing it. Either way, the solution is not a bigger catalogue of parts. DSOTEC is not another system supplier that gathers off the shelf components and sells a system. We look into each specific case, select every component through dynamic system analysis, and engineer the module to the performance you actually require.

Our approach

New design or redesign, the objective is the same: hit the performance spec, provably, with every component choice traced back to a dynamic system analysis, not a shelf.

Markets

Where sub micron motion decides the outcome.

Primary

Semiconductor equipment

Machine builders whose engineering teams focus on the machine as a whole, leaving module integration as a persistent bottleneck. This is our home market and our founder's background.

Expanding

Adjacent precision systems

Medical devices, photonics and optics, and defence optics. Anywhere a machine lives or dies on how accurately something moves and how quickly it settles.

Where the work is implemented

Our motion modules run inside the machines that build chips.

Wafer handlers

Fast, repeatable transfer without disturbing the wafer.

Die bonders

Placement accuracy at the micron level, cycle after cycle.

Inspection and metrology

Motion stable enough to measure against, not just move.

Laser scribers

Synchronised motion where position and timing must agree.

Pick and place

Move and settle fast, with no overshoot the part can feel.

How a project runs

From your performance envelope to a machine you own.

We start with the problem, not a catalogue. Requirements are defined precisely, the module is designed across every discipline at once, the first article is built and validated against a real acceptance specification, and the complete package is transferred to you.

Every project ends with you owning everything. Drawings, BOM, software, and parameters. There is no ongoing dependency on DSOTEC.

Scope and specification

We begin with your performance envelope. Requirements are pinned down before any design work starts.

→ Design specification, BOM, acceptance spec

Complete design and simulation

Mechanical, electrical, and software domains designed together, with dynamics proven in simulation before hardware is committed.

→ Simulation report, test plan

First article build and validation

A physical, tested module measured against the acceptance specification. Hardware and software you can put in a machine, not a slide deck.

→ Validated module, test report, documentation

Production handover

The complete package is transferred so your team can manufacture independently, with a commissioned axis and a signed acceptance protocol.

→ Commissioned axis, full handover package

About

Engineering conviction, not a portfolio.

Mariano Salvatierra Bellido

Founder and lead motion engineer

A mechanical engineer specialised in electro mechanical system design, shaped by hands on experience as an equipment builder and by original research on linear motor accuracy. The insistence on validating performance at the module level, not the datasheet level, comes directly from both.

The founder began as an motion control engineer at BESI Austria GmbH, a leading supplier of semiconductor assembly equipment for global industries, working first hand on the motion modules inside equipment for die bonding and advanced packaging.

That experience led into a master thesis at AAU in Denmark: a R&D project carried out in collaboration with TECNOTION B.V., a global specialist and independent supplier of direct drive motor technology, focused on how to minimise parasitic forces in ironcore linear motors. The work produced a validated characterisation setup and a methodology for isolating and reducing forces that quietly erode positioning accuracy.

That path, from equipment builder to first principles motor research, is where DSOTEC comes from. It is the reason the company treats a motion module as one engineering problem across mechanics, controls, and software, rather than a stack of components to integrate.

Tell us about your module.

We work best when the conversation starts with an engineering problem, not a spec sheet. Describe the module, the machine it belongs to, and what is not working today. We will take it from there.
