A copper clad laminate is disclosed to include a substrate defining a plurality of carrier zones for attachment of chips and having a plurality of barrier portions each arranged around at least one of the carrier zones for isolating the carrier zones. Thus, when tin sheets mounted between the chips and the carrier zones of the substrate become liquids in a thermal reflow process, the barrier portions of the substrate will stop an overflow of molten tin to prevent the chips from damage caused by a solder bridge problem.
