Hi JSeewald, You are very much right that there is difference between the solder pad with respect to IC pad. Since the Manufacturer suggests the same -- design also freezed to recommended dimensions.

Hi Djo, very much sorry to say that no gbx file is available with me (Customer not yet supplied). Sharing you image of stencil design.

Thank you both, it is not the good HLA design and this is why the deflection is needed to sit everything properly in the case. We did ask cust0mer(we are CM) to change it, I am just looking for a standard to support our claim.

Go with the machine manufacturer's recommendations. And remember there are no hard and fast keep out areas. You can go a little tighter than they suggest but it is risky.

Oh, I know nothing about SEO. You probably need a Web designer to talk to more than a bunch of Manufacturers like us. Good luck

We are designing a new PCB that will include a 0.4 mm WLCSP IC package. The OEM’s application-note for this package states ENIG; Au

I would need something from someone who has experience with custom WBH for Universal. I don't think those vendors have made WBH before. They would need to design it as well, I could provide gerber.

Ah okay, that should be pretty easy to do on the current board design. If overprinting doesn't work, then I might try a preform. I wasn't even aware that was a thing, I might be able to do some of our through-hole components that way if they are rate

Do you have the ability to add copper thieving or otherwise balance the design? We had a customer making LED boards with a terible inbalance. Some of the boards would "smile" so badly in the oven that the leading edge touched the top. They switche

If you are running resonable volumes of the board, redesign it with equal copper on both sides. One way of achieving this is to just run copper flood planes on both sides of the board, this is a fairly common technique in RF and noise sensitive analo
