Hi AJ, Just had a look though our parent company's stock on components, and even the smallest of diodes & transistors (such as DFN1006-2 package - roughly 0402)come on 8x4 plastic. All of the 8x2 pitch tapes are paper (EIA: 01005, 0201, 0402; JIS: 0

I am looking to discuss 0402 issues, specifically tombstoning/unsoldered. Any recommendations on pad size/spacing, stencil design etc would be helpful. Placement and reflow profile look good.

Do you have any information about the best standart for 0402" chip pad design. I have found differents recomended dimensions from IPC standart and manufacturer(AVX) . Which should be the best one? Thanks

Don't know if they "needed" embossed or not but....... I get an LED that is 0402 on embossed but, it is also at 4mm pitch as well.

Hello All We are going to run our frist 0402 parts soon. do I need to go to .005 stencil or will .006 work ? do I need to use a type 4 paste ? pad design does a standard rectangle work or the round pads ? Thanks in advance for any replies.

You can use regular paste and a .005 stencil will help reduce tombstones. It's just that easy. I run 0402's all the time without any problem, just make sure your profile is a good one!

IMHO it's caused by three things: 1) placement 2) placement 3) placement
