Testing for ionic
contamination has been around since the inception of the PCB. Ionic
contamination can lead to dendrite growth and corrosion. Contamination
can cause current leakage across insulating surfaces resulting in
shorts. Some common sources of ionic residue include plating
chemistries, flux activator, perspiration and more.
Specifically cited inMIL-2000A, the Zero-Ion ionic contamination tester is one of the industry’s most popular Resistivity of Solvent Extract (ROSE) testers, IPC-001 and IPC TM650 recognize ROSE testing as an approved method of determining the cleanliness of circuit assemblies. Today, in an environment where densely populated surface mount technology has become commonplace, and where ISO, TQM, Six Sigma, and other quality standards are commonplace, cleanliness verifications are frequently required and essential. The Zero-Ion g3 is the newest, most advanced Zero-Ion ever designed and we’re happy to offer this service to our clients.
