    • A method of making a thermally curable solder-resistant ink, which comprises the following steps: polymerizing an aliphatic diamine monomer having a long carbon chain, an aromatic dianhydride monomer, an aromatic diamine monomer having a carboxylic group, and an anhydride monomer having a carboxylic group in an aprotic solvent to obtain a polyamine acid; cyclizing the polyamine acid to obtain a modified polyimide; and mixing the modified polyimide and a curing agent to obtain the thermally curable solder-resistant ink. By the steps mentioned above, the thermally curable solder-resistant ink made from the method has a dielectric constant less than 3.00 and a dielectric loss less than 0.01 and thereby is applicable to high frequency electronic equipments. Also, the thermally curable solder-resistant ink has good electrical properties, folding endurance, solder resistance, warpage resistance, flame resistance, acid endurance, alkali endurance, good solvent resistance and low water absorption.
    • 一种制备耐热可焊性耐油墨的方法,包括以下步骤:聚合具有长碳链的脂族二胺单体,芳族二酐单体,具有羧基的芳族二胺单体和具有羧酸的酸酐单体 将其置于非质子溶剂中以获得多胺酸; 环化多胺酸得到改性聚酰亚胺; 并将改性聚酰亚胺和固化剂混合,得到可热固化的耐焊料油墨。 通过上述步骤,由该方法制成的可热固化的耐焊锡墨水具有小于3.00的介电常数和小于0.01的介电损耗,因此可应用于高频电子设备。 另外,可热固化的耐焊锡墨水具有良好的电气性能,耐折叠性,耐焊接性,耐翘曲性,阻燃性,耐酸性,耐碱性,耐溶剂性和低吸水性。
