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

The first issue I see is that you have a high potential of the 402 tombstoning.

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.

All of the Mydata machine comes with a standard library package; 0402,0603,0805,1206, soic8 and so on.

It's pretty much true, every company builds their own package database...usually on an as you go basis, meaning you create packages as you need them. If you bought the machine from MyData, it should have shipped with at least the basic packages in p

There is no difference in 0402�s on the bottom side than 0603 0805 1206. They will not fall off or tombstone, unless they where before you put them in the oven.

Actually 0603 is 8mm x 4mm pitch. 0201 and 0402 are 8mm x 2mm pitch. 0603, 0805, 1206, 1210 are 8mm x 4mm pitch. Tant Caps 3216 & 3528 packages are 8mm X 4mm pitch. 6032 and 7343 are 12mm X 8mm pitch. ICs, Diodes, Transistors are various sizes and d

Suggestions please... I have to place a number of 1206 chip resistor arrays on the bottom side of my PCB for wave soldering. The device consists of 4 x 0603 resistors in a 1206 package. The device is available with either concave or convex terminati
