HYDRON® Technology
HYDRON® is an innovative cleaning technology developed by ZESTRON. HYDRON® cleaning agents are single-phase, water-based, covering a wide range of cleaning applications, such as defluxing of PCBAs, power electronics, advanced packages, and wafers. HYDRON® Technology enables the complete removal of all contaminants from various electronic and semiconductor substrate surfaces.
Key Advantages of HYDRON® products
Single-phase formulation
HYDRON® cleaning agents are single-phase formulations with the following characteristics:
- Stable single-phase micro emulsion; no agitation required to mix or activate the cleaning agent
- Bonds to contaminants temporarily, resulting in easy filtration ensuring extended bath life time and low operating cost
- Excellent cleaning performance for PCBAs, power electronics, advanced packages, and wafers
Easy processability
HYDRON® formulation advantages for process handling:
- Excellent cleaning and rinsing in cleaning machines with limited mixing
- Single-phase formulation results in consistent concentration between wash bath tank and cleaning chamber
Excellent rinseability
Single-phase HYDRON® formulations provide excellent rinseability ensuring the complete removal of residues, thereby providing optimal surface characteristics for subsequent processes. For example:
- Using HYDRON® products in dip tank processes for defluxing of PCBAs or power electronics will ensure residue-free substrates
Process Control
HYDRON® cleaning agents can be monitored by ZESTRON process control products:
Working principle of HYDRON® cleaning agents
Conventional Surfactants
- Surfactants remove the contaminants from the substrate surface and permanently bond to the contaminants
- Therefore, regeneration by filtration is not possible and the cleaner is quickly depleted requiring frequent bath changes
- Surfactants remain on the substrate surface leading to issues with subsequent processes such as wire bonding or coating
HYDRON® Technology
- Active HYDRON® ingredients remove the contaminants from the substrate surface, but they do not permanently bond to the contaminants
- Once removed from the surface, they release the contamination so the cleaning agent can be regenerated by filtration ensuring an extended bath life time
- HYDRON® ingredients leave substrates residue-free
Regulations & Compliance
All HYDRON® cleaning agents are 100% RoHS & WEEE compliant. HYDRON® cleaning agent formulations are free of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrombinated diphenyl ether (PBDE) flame retardants.
