Attenna assembly for RF board

Electronics Forum | Fri Jan 29 15:39:04 EST 1999 | Chris Jackson

I have a recent design (1 component side only) that calls for 2 surface mounted antenna's (brass plated) to be mounted on a PCB. The problem arises when the PCB is 18x11.25 and has 15 to 20 PCB's in the pallet (IE weight, fixturing to hold the anten

i'm sure everyone has run into this at one point or another. I have a thin pcb .025 that is single up that has to be built on a pallet. does anyone have any tricks to the pallet design that will help to hold these boards down during the screen/ass

Your thinking is correct. Wave soldering pads that were designed for reflow can create problems: * Large pads used for reflow [too much solder] can create reliability problems. * Bridging [too much solder] creates rework. * Skipping & shadowing from
