Your peak temperature needs to be 20 to 30�C GT the melting point of the solder. What is the melting point of: * Tamura 60-30 paste? * Tin lead on your connectors? [You imply that it is 63/37, but is that correct?]

It is a FUJI Line with the machines: GP641 GL641 CP6 IP3 the oven is the smt Quatro peak. Moreover we have an AOI.

Trying to clean TACFLUX007 on reflow profile with 320C peak temp for 20 seconds. Anybody out there cleaning this stuff?

Pete, Holy crap 320C peak !!! What the heck are you soldering ?Is the residue charred, or brown ? I am familiar with TACFLUX009, is tack flux 007 NO-clean ? Need more info.....

I've seen this problem caused by the cool down. On a 7 zone oven I made a profile to peak at zone 5 to give some semblance of control to the cool down. The component can develope a big delta T, because of the difference of materials

To remove or Place a BGA in a BGA reworks machine , do I have to do a same profile as a normal Oven ( around 4.5 mins to Peak time ) or the conditions are only to get temperature needed to Solder or Remove ( no matters Time).

Hi, I have taken the profile.The peak temp. at the lead terminal is 219 degc, duration above MP 54 sec and duration 125 deg C-160 deg C is 60 sec.

The profile is enclosed.The PBGA is 37x37 mm.I am keeping the gap about 4-5 mm.The profile meets the solder paste spec.Peak temp is 211 deg C,Above melting point 77 sec. rate of heating

Dear Frank, could it be that your component legs are coated with a leadfree finish? This can have an inpact on soldering when your temp.peak in only 220�C and the melting point of pure Tin is 237�C. Best regards, Daniel

Questions are: * Is this 210*C peak temperature measured on the leads of the connector that do not solder well? If not, what is that temperature? * Do you have similar issues with other components on this board? * Do these floating connector leads t
