| WOULD LIKE TO DO RELOW OF 2 SIDED SMT BOARDS. USUALLY THE BOTTOM SIDE HAS RESISTORS AND CAPS ONLY. WHEN THE BOTTOM OF THE BOARD HEATS UP, THE PARTS ARE FREE TO MOVE AND ONLY SURFACE TENSION WILL KEEP THE COMPONENT FROM FALLING OFF. | CAN BOARDS BE

Two options: 1 Glue 2 Use a dedicated work holder with 'pockets' milled out to accommodate the components on the first side of the board after reflow. Some prefer a pallet that runs all the way through their process. So, these pallets: * Feature

Hi Steve, It sounds like your product will have many moisture-sensitive devices on both sides. You should be aware of the additional controls that are required to insure the reliability of these components in a double-side reflow application. The

Our company does not assemble boards but our customers do and 2 side smd with through hole is pretty common in our experiences.Our customers usually have already decided to glue the bottom side components and fuse them during the wave solder process.
