Many times the crystal supplier also has a package that already has epoxy bumps on them to allow th crystal to be raised off of the board. This is my preffered way since placing spacers on components can be time consuming and operators can and will

no there is lot of difference between both the alloys.. SN100C works better than SAC305... gives little more time to remove and replace the unit without completely loosing the Cu... but there are customers who still prefer sticking to SAC305... so th

2D SPI? Depending on the focusing height PTH inspection, or PTH solder joint inspection? Strip down if it has a granite slab in and turn into an engineering table for manufactured parts inspection? Stick a router head on it if you are really bored
