Is the issue observed related to a vertical fill parameter or non wet on the copper itself. victor -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Wee Mei Sent: Sunday, January 08, 2006 7:33 PM To: [log in to unmask] Subject: [TN] Solder Wettability Problem Hello, During assembly inspection, noticed that the solder joints on the 2 sided leads for Hirose connector, MQ172-3PA do not wet well. From the datasheet, it seems to be of phospher bronze. As I am not a chemical gal, is this the cause as we are using Sn37/Pb63 solder with liquid flux. Thanks in advance for your response.
