Hi All, One of my customer has provided a pcb design having common pad for 0402 and 1206 package(i.e 3 pads in the gerber, pad1,pad2 belongs to 1206 package and pad2,pad3 belongs to 0402 package) Will this create any solderability issue. Is anyone e

I am completely new to SMT design and for my next project I plan to use SMT for the first time. Since production volumes of the PCB's will be low, hand soldering is definitely an option, and will be necessary for my prototype PCB assembly. My proble

The pads you use for Reflow will be be fine for handsolder. Russ

Any ideas on what to buy? Only need to build surface mount protos, ability to rework. Is a rework station okay? Will subcontract production after design is proven.

You're correct. This design will have a record amount of 0402 rework for tombstoning and misalignments. Suggest that the pads on each end of all components be the same size in order to balance wetting forces during reflow.

I agree with the previous two replies. This is a perfect design....if you're trying to create a graveyard full of tombstones.
