Reconditioning and renovation of electrical and electronic devices

Once they have been correctly cleaned, machineries and production equipment can start operating again thanks to our electric device reconditioning technique. Nowadays it is often more convenient to buy a new device instead of fixing it. But that is not always possible, most of all when many expensive devices are damaged. We help you make the right and cheapest choice. Not only production chains, but also electric and energetic systems (like wind or photovoltaic systems) can be recovered and brought back to their normal operations. The degree of contamination, the classification of goods and burnt materials, as well as the presence of previous damages determine the choice for the most appropriate reconditioning activities for each system. After the intervention, the recovered good must regain a chemical cleaning degree that makes it reliable through time, and after possible recalibration operations, it must go back to its normal operation without any other intervention.

EXTERNAL RECOVERY

Cleaning of all surfaces with appropriate chemicals, with no dismantling needed.

RECONDITIONING

Interventions aimed at restoring a global chemical cleaning to the device that ensures reliable operations throughout.

RESTORATION

All the interventions that would normally include and complete reconditioning, that aim at reestablishing the machineries to their pre-damage operating characteristics.

The reactivation of electronic and electrical components depends, alike mechanical parts, on different factors. In case of a fire, it depends on the temperatures reached, which can be easily detected by heat-sensitive parts like cables, paintings and plastic parts. For floods or collapses, it depends on the presence of possible mechanical damages. The age and wearing of a component are also crucially important, as it is the availability of technical documentation, schemes, manuals and spare parts, as well as the device status relative to when damage took place and the following hours. Aside from all the other elements, in the following decreasing lists shows different degrees of recoverability depending on the status of the device during the damaging event:

Device status when damage occurred:

  • operating
  • switched on
  • switched off but connected to a power supply network
  • presence of UPSs and/or buffer batteries
  • connected to the power supply network that was not in use when damaged occurred
  • switched off and not connected to any power supply network

Device status after the damage:

  • devices are still working even after the damage occurred
  • operating devices were switched off and disconnected after the damage
  • devices that were switched off during damage were tested afterwards
  • devices connected to the power supply were immediately disconnected after the damage

Analyzing these elements makes it possible to check a good’s recoverability, and which technique to use.

Reconditioning methods for electrical and electronic parts

Pagina-16

Manual reconditioning through humid air

  • Identification and removal (or sealing) of semi-encapsulated components
  • Removal of compact components, that shall be treated individually
  • Hot-dip application of specific solutions through brushing
  • Application of the same solution on “hidden” points through high and low pressure guns
  • Rinsing with demineralized water
  • Pre-drying through oil-free air
  • Unsealing of semi-encapsulated components
  • Vacuum dry-out
  • Inspection of contacts and connectors
  • Re-assembling of compact components

Galvanic reconditioning

Is applied to complex electro-mechanic components, contactors and switches. Four different dips are normally carried out

  1. Dip in a variable-temperature alkaline solution This tank can be energized with ultrasounds
  2. Rinsing
  3. Removal of contamination and corrosion products. Dip in weak acid that can be energized with ultrasounds
  4. Rinsing
  5. Drying through oil-free air
  6. Vacuum dry-out.

Dry reconditioning

Suction through coating with conductive brushes, operators connected to the ground and antistatic bearing plane.
