Need helps on stacking chips

2017/3/1 4:06:50

I need to install two SMD chips (0805) at one location. I refered to IPC-HDBK-001, fIG 6-24. When I solder the chips side by side, the ceramic side which is placed againgst solder pad- is already touching the solder. While I complete the solder joint, the solder fillet is too close to deposited element. ( As distance between end terminations is more the inner gap between solder pads) My question is :

1. Does any one know a vendor who can supply 5-sided terminations ( similar to Chip Capacitors) for thick film resistors? 2. Which one is less evil: Piggy back chips( not recommended by IPC) or solder touching the component body? 3. Any other idea?

I will appreciate your time for advice.
