PCB repair and rework Description:

Allgood Technology is equipped with a range of tools to rework and repair printed circuit assemblies to IPC-A-610 or your own company standards.


Major Plant List:


    Metcal MFR-1351 Desoldering Station for through hole desoldering.


    Leister HotJet system for SMD rework using a variety of shaped nozzles – typically for rework of QFP and other multilead packages.


   ERSA IR550/PL550 system. This is a complete component removal and refitting system using infra red heating to gently remove components from 1mm square up to approx 70mm square – typically BGAs – and includes a split vision optical alignment system to permit rapid and highly accurate replacement of devices. 


The ERSA has sophisticated temperature monitoring and profiling controls so that a thermal profile closely replicating that of the original assembly process can be established and stored. This gives repeatable process control that reduces undue thermal stress to a minimum. The system is equipped with under component video so that the soldering point can be seen in real time – especially useful for BGAs.


Prebake requirements: Allgood Technology firmly believes that large components and assemblies that have been in the field for some time should be prebaked prior to major rework to drive out absorbed moisture which can cause PCB or component damage.  We have a Gallenkamp baking oven for this purpose and recommend at least a 24 hour bake at 125 degrees prior to starting the job. If IPC or other specifications override this time then these will take precedent. Customers should be aware that prebake can add up to several days to a jobs’ turn round.

Warranty: Rework is by its nature subjecting the PCB and components to additional heat and cool cycles beyond those intended at manufacture so although every care is taken unfortunately we cannot guarantees this aspect of our work beyond general workmanship.
