| Conformal Coating: Chất phủ mạ ABchimie của Inventec 2018-12-04|
ABchimie’s conformal coating are specially developed to ensure high protection to PCBAs from their environment.
They improve and extend the working life and reliability of performance. They protect PCBs against harsh environment as salt spray, humidity, temperature, solvent and dust in general, a thin layer (25 to 50 microns). These environmental conditions can cause damage as corrosion, current leakage and failure.
The complete range proposes different base of raw materials:
|- Acrylic||- UV curing material (Acrylate urethane)|
|- Silicone||- None VOC silicone product|
|- Urethane||- 100% content|
|- Aqueous urethane|| |
An alternative to conformal coating is 3M NOVEC Electronic Grade Coatings. These are fluoropolymer coatings for challenging components in PCBA's, LED Lighting displays, MEMS and flexible circuits. They also provide anti-stiction properties for MEMS wafers.Inventec offers COMPATIBILITY of ECORELTM solder paste with our range of coatings, achieved by the compliance with the BONO test - to assure our residues -are chemically inert and reach excellent adhesion levels in No-Clean processes.
- AB Chimie AVR-80-BA (Acrylic Removable Conformal Coating): AVR80 BA conformal coating is a non toxic, flexible transparent acrylic coating for the protection of electronic circuitry formulated to meet the highest resistance requirements. AVR80 BA is designed to be removed with ABchimie SND .
- Conformal Coating AB CHIMIE Acrylic thinner DVA BA: DVA BA is a non toxic solvent blend designed for use with all acrylic based conformal coatings. Especially used for AVR80 BA acrylic coating. The main uses of the thinners is to dilute the coatings for use in dip and spray coating. DVA BA R is a specific thinner which permit to reduce thinner quantity in the mix with AVR80 BA to have higher thickness on the pcb when you spray with a gun (mix is 1:1).

WHY USE ABCHIMIE CONFORMAL COATING?
ABchimie proposes a high quality of product
but also proposes ready to use product. You can ask your specific viscosity for your machinery for the same price. We bring you all technical support to help you in your process. Be present and help you is one of our
major involvement to earn your trust.
HEALTH AND SAFETY
ABchimie is very involved in these subject, for this reason we are always looking Eco-green alternative when it’s possible. AVR80 BA is the green alternative of common acrylic conformal coating,
this version is no toxic (no labelling). The specific solvent used in this formulation permit to protect people.
This reference is now very well known and used in large quantity in automotive, military and industrial application. Regarding new generation of conformal coating we proposeABchimie526 UV and ABchimie746 E UV which contains no VOC and cure with UV mercury lamp but also with a LED which permit to replace the mercury lamp but a LED lamp 395nm.
1. SPRAYING – Usual method. Very goods results on plane surface.
2. CANS – recommended for repairs, small and medium series.
3. SPRAY GUN – highly economic, hand spray using a spray or aerosol can. All coatings can be applied in this way.
3. SELECTIVE DEPOSIT – Different existing machineries: ASYMTEK, PVA, USI, DIMA . High performance level for mass production, reliability of deposit. All coating types can be used if the correct dispense head is selected.
4. DIPPING – To ensure presence of conformal coating even under components. it is limited to materials that do not cure quickly by moisture, light or oxidation.
HOW TO CHOOSE A CONFORMAL COATING?
You will have to consider the curing method determined by the coating selected, air dry, oven dry or UV light cure. The liquid coating should thoroughly wet all surfaces and cure without leaving surface defects. Epoxies are especially sensitive to surface defects, it can also shrink while setting and may lose adhesion as a result In addition; It is very important to define well your needs:
- PCB environment?
- Electric requirement?
- How you will apply it?
