Hi Glenn,

Sincere apologies for the delay in my response. I was discussing your query internally. Please find the response of our experts below -

We normally provide SMT guidelines but do not provide details such as amount of solder paste. This is because the dispense of the paste, volume etc. will depend upon customer process and target paste manufacturer recommendations.It is recommended that you reach out to paste manufacturer with the stencil design and get their recommendation.

The paste mask (or stencil) opening can be the same size as PCB pad size, as shown in Figure 32 in the App. Note. The mask (or stencil) thickness, we use 5 mil thickness for our SMT for BLR test, without any problem.

Best Regards,

Apurva

Hi Glenn,

Thank you for contacting Cypress Semiconductor.

We need some clarification in order for us to provide an accurate response.

  1. metal mask guide – is it mask guide for Silicon?
  2. smt guide – are you referring to Land pattern?

Best Regards,

Apurva

Hi Glenn,

I am not clear about your previous response. You had requested for the metal mask guide and smt guide in the original query. Right?

Quality team needs clarification regarding the original request.

1. By metal mask guide, do you mean mask guide for silicon?

2. By smt guide, are you referring to land pattern?

Regards,

Apurva

Hello Apurva

Do you mean "At center slug, the stencil should also has small multiple openings with solder paste coverage about 40 – 70% of the exposed pad area to prevent bridging between the center slug and pins." ?

Thanks and Best regards.

Hello Apurva.

I  am poor to use english.

They wish to know amount  How much the solder paste.

For applying it, they need the figures how wide the space of the paste mask is.

Thanks and Best regards.
