So I've though of two other candidates for conveyors inside reflow ovens aside from metal screens or metal link chain (the latter is very common in reflow ovens):
1) A conveyor belt made from closed cell small or micro-pore silicone rubber that is filled with carbon black to make it conductive (antistatic). The belt has little hemispherical divots to allow the parts to nestle into and hold them as they travel along.
2) A metal belt made from shim-thickness steel (1045, 1080, 304/308/316 stainless) foil/sheet (0.002" - 0.010") that has a series of holes punched in it at regular spacing. The hole centers are based on a FCC (face centered closest packed) or hex pattern. On the outside you could have holes along the edges for traction (kind of like old greenbar printer paper they used for spreadsheets back in the day).
