we have ordered 40 pcs of SMJ320C31GFAS60, when the parts is coming, we see different plated in the same datecode.
34P DC:1842A →31P is gold plated, 3P is Tin plated.
6P DC:1844A → 4P is gold plated, 2P is Tin plated.
so wondering how this happened, is there any document or QA check, it can not be only 3p/2p different in same batch.
gold plated will have better quality compare to TIn plated?
do you have any document that both plated will come at same dated code, performance is same for gold plated and tin Plated? we just need the documents to approve this is normal.
