HDMI Connector poor contact | 10 August, 2004

Hi, Has any body experienced the problem of poor cotacts on HDMI connectors. The connectors pins are gold plated and we see some kind of white residue on the gold pins.How to check if this is a flux residue?We are using No Clean flux in wave soldering.Cleaning the residue with solvent helps but it is very difficult to clean due to design of the HDMI connector.

Praveen,

White powder residue can be produced if you clean the No clean flux residue with isopropyl alcohol. Check whether you are using any IP for local cleaning. In case you want to clean the noclean flux residue ( as per the requirements of contamination standards ) it should be done using the manufacturers recommended solvent for the solder you are using.

Aqueous cleaning solutions using saponifiers and surficants can sometimes be used to clean NC flux residues. Search the fine SMTnet Archive for background and supplier suggestions.
