Key distinguishing points (essential for communicating with your SMC business clients)
1. Thermosetting sheet**
FR4, GPO-3, and SMC sheet all belong to this category.
✅ High temperature resistance, small size creep, excellent insulation
❌ Cannot be repaired by hot melt; There is solidification shrinkage during molding, and the anisotropic shrinkage of the felt based board (GPO3/SMC) is significant, resulting in lower dimensional accuracy compared to fiberglass cloth laminates**
2. Thermoplastic fiberglass sheet**
✅ Can be bent, welded, and recycled; Batch extruded sheet has good consistency in size
❌ High temperature is prone to creep and slowly deforms under long-term load; The insulation temperature resistance is generally lower than that of high-end thermosetting sheet
