Hello,

 

My customer are doing a PCB design with HMC986A and they have some questions about this.

Please refer below questions and let me know your opinions.

 

Q1) About PCB

   1-1) As your datasheet(Page 9 Figure1 and Figure 2), Pattern Thick size are fixed to 0.127mm or 0.254mm.

            And they want to make their PCB with Rogers3003.

            For this reason, they want to know whether they can change Pattern Thick size as the kind of materials.

           Would you confirm whether they should use a fixed thick size in datasheet or  can change a Pattern Thick si

   1-2) What is a material of Moly Tab with 0.15mm Thick in your datasheet (Figure 2)?

 

Q2) About PCB Material

   2-1) Should they use Alumina as a Pattern material only?

 

Q3) About how to handle a assembly product with HMC986A

  3-1)  After wire bonding between HMC986A Die and PCB, do you have any precaution about handling this PCB with HMC986A die?

          For example, "Don't touch assemblied HMC986A die with bare hands"

 

Please advise me.

 

If you have any questions, please let  me know.

 

Regards,

Se-woong

 

PS.  Please refer below figures in Datasheet.
