摘要: A direct chip attach module (DCAM) 10, comprises of one or more electronic components 30, electrically bonded to a printed circuit 40, on a substrate 20. The DCAM 10, is bonded to an electronic circuit assembly by connection pads 50, formed on the edge of the DCAM substrate 10. This enables easy visual inspection of solder joints between the DCAM and the assembly.DCAM substrates 10, are initially formed in a panel form 70, and vias 50, are drilled and filled with electrically conductive media 55, at predetermined connection points. The DCAM 10, is then excised from the parent panel 70, and the cut vias provide connection pads 55, along the edge of the substrate 10.

摘要: A lightweight bag holder made from at least one section. The section of the bag holder has a first vertical edge, second vertical edge and a bag holding edge. The bag holder has a releasable connecting means which allows the first vertical edge to be moved away from the second vertical edge to form a second mouth. The second mouth allows lateral removal of the bag from the bag holder. The size of the first mouth of the bag holder can be varied to accommodate different sized bags.
