I said: "Our electronic circuit board fabricators seal the boards in moisture barrier bags [MBB]. We discontinued the use of desiccant bags in these MBB because of concerns about the desiccant releasing materials that would affect the solderability

Nice to have you back on SMTnet. Some of the newer folk have missed-out on the solid contributions you�ve made to the Forum. The chicken wire cleaning basket was a classic!!! [It�s a shame that the folk at SMTnet can�t recover those files.] We bu

Another variable is whether the ground pads have proper thermal reliefs. If the pad has solid ground plane around the perimeter, the heat being applied will quickly dissipate to the surrounding metal. A proper relief of the pad will prevent the hea

Layer 2 is the ground plane layer of a 4 layer board. After installing a 2.5 mm DC power jack and 0.1 center SIP header by hand, the ground pin disconnects and causes an open. My board supplier said they passed Electrical Test. Prepreg was within

Pavel You're correct that you should consider the point loading of your placement, wave and other machines. I've put shops above the ground floor of buildings. Equipment suppliers are the best source of information about these requirements. BR, dav
