I have been a loyal customer of Sumika Electronic Materials for many years now and I cannot recommend them enough. The quality of their products is outstanding and their customer service is exceptional. I recently had an issue with one of their products and their team went above and beyond to resolve it promptly. I am grateful for their dedication and professionalism.
