Placing large chips with tons of pins on a circuit board that has had solder paste applied needs precision to get it in the exactly right place.
Can't do it with just forceps, which are fine for smaller parts.
- russdill 3y agoSmaller parts are so much easier with a vacuum pen. You just need expensive tips for 0402 and smaller.
- ilyt 3y agoThey tend to jump into place thanks to the soldier surface tensions so you don't need to be exactly right. It's just more convenient using this.
- RF_Savage 3y agoIt is less about them jumping and more about it even being possible to use forceps to begin with to place them without disturbing pins or paste. For example TQFP-144 and fBGA256 parts are hard to place with forceps alone. Let alone larger parts.
