Title: Circuit substrate and process for producing the same
Inventor: GOTOH TAKESHI
IPC: H05K3/38
Filed: 2000-05-26
Abstract: PURPOSE: A circuit board and a method for manufacturing the same are provided to achieve a ceramic substrate and an Al or Al alloy circuit formed on the ceramic substrate, at a low cost while keeping its high reliability. CONSTITUTION: A circuit board is formed by a method of bonding an Al plate or an Al alloy plate to a ceramic substrate by using the Al-Cu type bonding material under heating, followed by etching, or a method of bonding a circuit pattern punched out of an Al plate or an Al alloy plate to a ceramic substrate by using the Al-Cu type bonding material. In either case, the bonding temperature is within a range of from 540 to 640 deg.C. However, the proper range is different depending upon the composition of the bonding material(3,5). In a case where the component having a relatively low melting point such as Zn or In is incorporated, or the content of Cu or Mg is relatively high, the bonding will be satisfactorily carried out at a temperature of at most 600 deg.C. On the other hand, if the bonding temperature exceeds 640 deg.C., soldering defects (moth-eaten phenomenon formed on the Al circuit) are likely to result. Further, it is preferred to apply a pressure of from 1 to 100 kgf/cm¬2 a direction perpendicular to the ceramic substrate during the bonding.
