Cleaning PCBs before conformal coating removes potentially harmful and unknown contaminants from the board's surface resulting in better adhesion of the conformal coating and thereby preventing delamination. Cleaning PCBs can ultimately prevent issues like leakage current, electrochemical migration and coating failures. From a production standpoint, it can help ...
The corrosion of Nickel-Palladium-Gold (Ni-Pd-Au) finish terminals in humid environments is known to be reduced with the application of a conformal coating such as acrylic. Corrosion has a higher rate of occurrence around the terminal 'knee' of a surface mount component, which may be reduced with the application of ...
A customer called the Helpline seeking advice for cleaning no-clean fluxes prior to applying a conformal coating. The customer's assemblies were manufactured with a no-clean rosin based solder paste (ROL0) and were cleaned with an isopropyl alcohol (IPA) wash. After cleaning, a white residue was sometimes found in areas with high paste ...
The set up of a turnkey conformal coating production line or facility, whether it is a batch or inline process, has many similar characteristics. Whether the coating application is based around a high volume selective coating robot, a batch dip coating system or a spray booth, the process requirements tend to be the same. This bulletin reviews ...
As the proliferation of modern day electronics continues to drive miniaturization and functionality, electronic designers/assemblers face the issue of environmental exposure and uncommon applications never previously contemplated. This reality, coupled with the goal of reducing the environmental and health implications of the production and disposal of these devices ...
Reflow Process for BGA pitch 6,5 -- Hi SMTnet. It is possible to reflow BGA's 0.65 pitch with a convection oven that only have heating zones on one side (topside) or is it a must to have heating zones on both sides in the oven (top and botton).
