摘要:
A non-halogen active agent for a flux is a sulfonate formed by a sulfonic acid reacting with an organic base. The sulfonic acid can be an alkyl sulfonic acid, alkyl disulfonic acid, hydroxyl sulfonic acid or halogenated sulfonic acid. The organic base can be an organic amine, carbamidine, imidazole, phosphorus. The non-halogen active agent for a flux has the advantage of high activity and low corrosion.
