Flux Residue Causing Test Issues

The test engineer on the other hand has to live with the residual flux and its effect on test probes. There are a number of solder/flux vendors who have formulated "no residue" fluxes that can help. They may cost more than conventional "low residue" flux but can save the customer in the long term from the hidden cost of re-test and rework.
