PCB – Assembly cleaning – Ultra-fine cleaning in electronics production

The cleaning systems of the EVO PCB series are compact single-chamber systems for ultra-fine cleaning of electronic assemblies and components.

This generation of cleaning systems combines highly efficient Miele industrial machines with our proprietary MATTHES Recycling System (MRS) to create a precise and cost-effective overall solution.

Permanent, fully automatic measurement, control and re-dosing of cleaning media guarantee maximum process reliability and quality.

Reproducible cleaning quality

Especially for high-quality assemblies in the medical, automotive, defence and aerospace industries, optimum cleaning results are absolutely essential to avoid rejects in production and malfunctions in use.

The thorough removal of flux residues, resins and other production residues on printed circuit boards serves as ideal preparation for subsequent processes such as bonding, coating or lacquering.

Optimal cleaning of misprints (misprints) helps you to save valuable resources and costs.

With the precision cleaning systems of the EVO PCB series, you are perfectly prepared for the constantly growing demands which the cleaning of assembled and unassembled PCBs brings with it.

Features and technical details

Capacity (euro cards 100 × 160 mm): 76 pieces with standard
upper and lower basket O500 (37 pieces) / U500 (39 pieces)

Due to their more compact design, the cleaning machines of the EVO PCB series can be optimally integrated into existing process environments.

Key features

PerfectTouchControl

Chemical-resistant glass surface of the operating and programming unit

PerfectSpeedSensor
Spray arm monitoring

Reliable cleaning performance by monitoring the spray arm speed

PerfectFlow

Media and temperature independent ultrasonic dosing volume control, reproducible cleaning quality through precise dosing of all media

PerfectPureSensor

Integrated conductivity measuring module for monitoring the final rinse phase

PerfectHepaDrying

Optimum drying results, free from unwanted particles and suspended matter from the room air

TOP feature of the EVO PCB PREMIUM

PerfectLiveControl powered by Zestron Eye or KYZEN Analyst

Digital real-time concentration measurement, live monitoring and automatic re-dosing in the media inlet. Process-related fluctuations which lead to a reduction in the concentration of the cleaning bath are compensated fully automatically. Water and cleaning concentrate are supplied in real time and ensure optimum process reliability.
