Part Number: TPS65101

Hi

we bought TPS65101PWP from mouser, the D/C:1816, and now the solderability test failed which cannot use on our product.

we contact mouser that need RTV,but mouser said that need we to contact directly :

The supplier offers the E2E forum, https://e2e.ti.com/, for technical support.

If the customer has contacted or does go to E2E and a TI employee determines the board/IC needs to be

returned, please include the link to that thread as it will speed up the RMA process.

we need TI's support that we can process the RMARE_ ABB out of DC Material Approve---SKID ID_26202960.msg

    Hello,

    Are there any special requirements in your soldering/assembly process that are not met by TPS65101PWP? How does this device fail in the solderability test? I am not able to understand the failure from the message you attached. The reason I ask is that this device is in volume production at many customers and I am not aware of any specific issues with soldering it to the board.

    RMA and returns needs to be handled thorough the supplier where you purchased the device.

    Kind Regards,

    Liaqat

    Hi Liaqat,

    you can find the picture in the attached, the bonding pad are not fully tinned.

    Actually I am the buyer ,if you need more details, I will ask help for my SQE. and as my supplier told us, I only can process the RMA with them after TI Team can determine the material can be returned or you can provide related report， thanks in advance.

    Hi Rachel,

    I had seen this picture in the message you had sent earlier but I am not sure what the real issue is. Are you suggesting that the device is not as per datasheet specifications? How can we be sure that there is an issue with these devices and not the soldering process itself? We have many customers using this device in high volume applications and I am not aware of any soldering problems with this device.

    We are not in a position to provide any guidance about the returnability of the material. This is not a technical issue but rather purchasing/RMA related so I suggest to please directly work with the distributor where you purchased the devices for any returns.

    Kind Regards,

    Liaqat

    Hi Liaqat,

    Never mind the RMA process, I will work with distributor for it.

    the only question is the poor welding, cannot be tinned completely which can showed in picture. our soldering process is no problem because we have tested many times for it and also test many other devices . We also have bought the device TPS65101PWP from TI directly which solderability test is passed.

    So, I think there has issue which I show to you , maybe there has effect for improper Storage Conditions or anything else, but at present, we cannot use this devise.

    Hi Rachel,

    Thank you for your response. If you have bought and successfully used the same device in the past and nothing has changed in your assembly, process than it is possible that this particular batch you have bought has some issue due to improper storage or some other contamination. At the time of shipment from TI, we would not expect to have these issues so please do work with the distributor to return the devices to them directly. Thank you for your patience and understanding.

    Kind Regards,

    Liaqat
