Rework is the process of removing a defective component from a circuit board and replacing it with a new device.

Hand rework
  • Smaller, simpler devices are removed and replaced by hand.
  • The skills required to successfully perform hand rework without damaging the device or PCB (Printed Circuit Board) are gained with training and practice.
  • We use the IPC-A-610 standard to ensure consistency and quality of all rework performed.
  • We have an in-house certified trainer for IPC-A-610 and our people receive regular training.
BGA rework
  • Loop Technologies uses rework technology including a Zevac Onyx 29 BGA rework machine and a BX100 two-dimensional x-ray facility.
  • This equipment enables us to provide an extensive high quality rework facility for virtually all SMD (Surface Mount Devices) components using either lead or lead free solders.
  • Our expertise in this area is recognised by equipment manufacturers and we are regularly called on to assist with rework of circuit boards that require additional work after the standard manufacturing process is completed.
Key features include:
  • Repeatable positioning accuracy of 5 μm 3 sigma
  • Closed loop force placement accuracy of 0.01 newton (1g)
  • Board thicknesses up to 6mm multilayer
  • Maximum component size of 75mm x 75mm
  • Maximum board width of 510mm, length virtually unlimited
  • High level of automation and easy placement for BGAs as well as gull wing and J leg devices. Ideal for processing modifications or small production runs
  • Automated removal of RF shields, SMD sockets and connectors
  • Focused nozzle capability allowing re-work where component density is a factor
  • Two-dimensional x-ray inspection machine
RoHS compliance

Loop Technologies uses appropriate controls to ensure compliance to the Restriction of Hazardous Substances EU directive 2002/95/EC is maintained.

These controls include:

  • Compliant componentry labelled and stored separately from non-compliant components
  • RoHS compliant customer product is tracked and segregated within the information management system to ensure that only RoHS compliant components are used within the repair process
ESD safety

For the work we do, an electrostatic-free working environment is essential. We follow industry best-practice for ensuring our customers’ product is kept safe from ESD damage.

Safety features of our work environment include:

  • A dissipative floor surface (106-109 Ω) that is consistently maintained
  • Wrist straps and heel grounds, which are used by employees working within ESD-safe areas
  • Daily testing, which is recorded and monitored
  • ESD-safe chairs and trolleys
  • Work benches with dissipative grounded surfaces
  • ESD-safe dustcoats
  • ESD-safe packaging
  • ESD-safe component storage
