Part 3 - 𝐀𝐃𝐇𝐄𝐒𝐈𝐎𝐍
❌ A conformal coating that doesn't adhere… is no longer a protective coating.

𝐓𝐡𝐞 𝐩𝐫𝐨𝐛𝐥𝐞𝐦: Delamination, shrinkage, and uncovered areas result in an immediate loss of protection.

🔎 𝐌𝐨𝐬𝐭 𝐜𝐨𝐦𝐦𝐨𝐧 𝐜𝐚𝐮𝐬𝐞𝐬:
🔘 Contaminated board (flux, oils, dust)
🔘 Poor substrate wettability
🔘 Moisture-absorbed FR4 (inadequate storage)
🔘 Process residues (poorly controlled no-clean flux)
🔘 Insufficient surface energy

𝐒𝐨𝐦𝐞 𝐬𝐨𝐥𝐮𝐭𝐢𝐨𝐧𝐬 𝐭𝐨 𝐜𝐨𝐧𝐬𝐢𝐝𝐞𝐫:
✔️ Implement an effective cleaning process (validated process such as ionic contamination testing)
✔️Check surface condition (wettability test)
✔️ Dry the boards (baking if necessary)
✔️ Optimize storage conditions (humidity control)
✔️ Match the coating chemistry to the substrate

Over 3/4 of adhesion issues stem from poor substrate preparation. Have doubts about your cleaning or preparation process? Let's talk! 📞

Troubleshooting - 3ème partie -𝐀𝐃𝐇𝐄𝐒𝐈𝐎𝐍
❌ Un vernis qui n’adhère pas… n’est plus un vernis de protection.

Le problème :
Décollement, retrait, zones non-couvertes sont une perte de protection immédiate.

Les causes les plus fréquentes :
Carte contaminée (flux, huiles, poussières)
Mauvaise mouillabilité du substrat
FR4 humide (stockage inadapté)
Résidus de process (no-clean flux mal maîtrisé)
Énergie de surface insuffisante

Quelques pistes de solutions :
✔️ Mettre en place un nettoyage efficace (process validé type ionic contamination)
✔️ Contrôler l’état de surface (test de mouillabilité)
✔️ Sécher les cartes (baking si nécessaire)
✔️ Optimiser les conditions de stockage (humidité)
✔️ Adapter la chimie du vernis au substrat

Plus de 3/4 des problèmes d’adhésion viennent de la préparation du support.

🔍 ISO 9001 : pourquoi est-ce important dans la protection des cartes électroniques ?

Quand un client choisit un vernis de tropicalisation ou une résine, il recherche une performance technique et attend également :
✔️ de la régularité
✔️ de la traçabilité
✔️ de la stabilité dans les fabrications
✔️ une démarche d’amélioration continue

Ce sont précisément les objectifs de la norme l’ISO 9001.
Cette certification encadre l’organisation de la qualité afin de garantir des processus maîtrisés et une production suivie à chaque étape.

Dans des secteurs exigeants comme l’automobile, l’aéronautique, le ferroviaire ou la défense ; cette rigueur de process fait aussi la différence aux nombreux industriels qui nous font confiance.

Part 2 🫧 BUBBLES
❌ Too many bubbles in your conformal coating? It’s never “just cosmetic.”

The issue:
Bubbles can directly compromise PCBA protection:
➡️ unprotected areas
➡️ increased risk of corrosion or electrical discharge

🔎 Most common causes:
• Air ingress in the application circuit (fittings, hoses, dispensing head)
• Incorrect pump settings (pulsation, cavitation)
• Product over-agitation or insufficient degassing
• Inappropriate viscosity
• Micro-contamination on the substrate causing air entrapment

Some practical solution guidelines:
✔️ Check the complete sealing of the dispensing circuit (from tank to nozzle)
✔️ Use a diaphragm pump to reduce air introduction
✔️ Degas the product if necessary
✔️ Adjust dispensing speed and pressure
✔️ Improve substrate wettability

⚠️Too many bubbles are usually a warning sign of a process issue, not a product issue.

And not all bubbles are the same.
Each coating line has its own specificities, which is why expert analysis matters.

📅 Public holiday notice – Office closed on May 25th

ABchimie will be exceptionally closed next Monday, May 25th, due to the French Whit Monday public holiday.

In France, this day is also commonly associated with the “Solidarity Day”, introduced after the 2003 heatwave to support funding initiatives for elderly and disabled people.

We will get back to you as soon as possible on Tuesday, May 26th.
Thank you for your understanding.

☀️ Sharing Meeting & Celebration of Achieved Goals

Under Thursday’s sunshine, we had the opportunity to celebrate ABchimie’s strong results for April with a team lunch on the terrace.

The beginning of the afternoon was then dedicated to a sharing meeting where each department reviewed:
✔️ the positive achievements
✔️ the challenges encountered
✔️ possible areas for improvement

A great way to maintain a global vision of our activities, brainstorm solutions together and continue building a culture of continuous improvement.

Jean-Pierre also took the opportunity to warmly thank Véronique Resseguaire for her professionalism and her 15 years with ABchimie.
