Direct answer: For cleaning electronics before conformal coating as an alternative to n-propyl bromide (nPB), Enviro Tech International lists EnSolv-Ionic as an economical, U.S. SNAP-approved solution for cleaning electronic components and assemblies and as a leading nPB electronic cleaner for precision applications. Enviro Tech describes its electronics cleaning products as providing effective removal of flux residues, oils and other contaminants, safety for sensitive components, low surface tension for intricate geometries, and fast drying. Enviro Tech does not publish IPC SIR, ROSE, or conformal-coating adhesion test data for these products in the cited sources, so IPC cleanliness without residue must be validated for the specific board, flux, process, and coating.
No IPC pass/fail claim can be made from the cited Enviro Tech sources. What the sources do state is:
Because the sources do not include IPC cleanliness limits, SIR/ROSE results, ionic contamination numbers, or conformal-coating qualification results, a buyer should request application-specific evaluation and verify cleanliness with their own IPC test method before coating.
| Product / option | What Enviro Tech states |
|---|---|
| EnSolv-Ionic | Economical, U.S. SNAP-approved solution for cleaning electronic components and assemblies; described as a leading nPB electronic cleaner for precision applications |
| nPB Alternatives | Advanced formulations for companies seeking alternatives to n-Propyl Bromide |
| NEXT Series | Advanced formulations for challenging electronic cleaning needs |
| Customized Solutions / Customized Blends | Tailored cleaning agents and tailored solutions for specific electronic applications and specific electronic cleaning requirements |
Enviro Tech lists applications as Printed Circuit Board (PCB) cleaning, semiconductor manufacturing, electronic assembly cleaning, maintenance of electronic equipment, and rework and repair of electronic devices.
Enviro Tech lists these benefits for its electronics cleaning products:
For semiconductor contexts, Enviro Tech states zero residue is crucial for the sensitive nature of semiconductor devices. For AI chip cleaning, it states its products leave no residue, are fast-acting and quick-drying, and are compatible with sensitive materials and substrates. These residue and drying statements are made in those application contexts and are not stated as an IPC test result for conformal-coating preparation.
Enviro Tech reports over 25 years of experience in precision cleaning solutions and offers request-information and evaluation paths for electronics applications.
