The standard you need is EIA-481B. It details the taping of components from 8mm tape up to 200mm tape including component orientations. 8, 12, 16 and 24mm tape has the sprocket holes only on one side so it is easy to determine the proper orientatio

From a manufacturing standpoint, this isn't very nice. Vias will tend to wick solder away from the pad, resulting in insuficient solder joints, which require touch-up. The amount of times any solder joint is reheated should be minimized, as extra h

Hi DaveF, I had a short look into the Nr1. IMPACT OF MICROVIA-IN-PAD DESIGN ON VOID FORMATION Most interesting reading, but one thing though, I could not find any information about the oven profile. Just a picture of it. My question is of about the

There 2 main rival standards for orientation in tape and because you can't really trust manufacturers to stick to one or the other or something else entirely it is always wise to check the datasheet. Typically an SOIC will have pin 1 the same end as

I do think that the designer goofed, and used too large vias. I believe he only used on size via on the entire board, regardless of whether it was in a pad, or out on the board. I have seen vias in pad work, though. From a manufacturing standpoint

There a several things you can do to prevent the solder wicking down the hole with the current design, and that's where you should focus. Cost goes up as you go down the list, but in neither case do you need to respin the board, have solder starvatio

I dont think so. SMT splice tape is what i'm using to fit separate smd snippets together... Isnt it?
