HI Adeel the following is a brief summary of wave and reflow: wave: components are placed first, with the SMDs requiring gluing down. the board is then passed over the solder wave at an appropriate rate. reflow: components are placed on top of pads which are pasted with solder. the board is

Hi Adeel, If you've got a very densed board, you may consider reflow soldering on both sides. The footprints for reflow are smaller and you can gain much free space for the tracks. The disadvantage is that it's more expensive but you are free to place your components as you wish. The

some people like the assy dwg to look different than the silkscreen for example someone may prefer on the assy dwg to have all the designators 'inside' the component outline this way they are completely unambiguous on a silkscreen the designators are often 'outside' the outline so that you can
