It depends on the thermal mass of your assemblies (boards and components). Generally, if boards are small with few layers, the additional mass of components may have a significant impact on reducing the peak temperature. If boards are larger with s

Awhile back I faced a few problems because of that. To solve the problem, my only concern was about the peak temperature to assure that the alloy got melted. Peak temperature between 230°C and 235°C can assure that and usually is inside the sodler pa

What??? You don�t have enough things to monitor? The origin of some profiles is mysterious. It�s probably good to try to understand such mysteries. Certainly, the important determinants in the design of your reflow profile are: * Paste you�ve sel

Hello, in my SMT process I have some problems with the solderability (look like dewetting) on a PCB with finish HASL Lead Free with a composition that is melt at 230 degree Celsius. My oven is with vapor phase and the peak temperature is 230 degre

Delta T is the temperature difference between the lowest and highest temperature between measurable components at any point within the reflow process... taking into account the delay time for saturation from leading to trailing edges of the product.

Thanks for your response, yet to try with RTS Solder profiles, Have you any additional comments on this RTS Temperature specifications like Time above liquidus, Peak temperature if any..??

Hi Steve, To my opinion your peak temperature is a little low. If you are sure that the BGA (especially the balls under it) reaches this 205 degrees then it should be OK, but if you measured somewhere else on the board then it's probably better to r

We are currently using Oven Rider (ECD) to "verify" just the conduct of the peak temperature; we define which product is the higher runner for this line and then with the settings for this product (already profiled with thermal couples attached to th

Hi, Now in my wave the PCB TOP Side temperature before WAVE is 110 - 115 DegC and the Peak temp in the wave is 240 - 245. These informations are for an 63/37 Alloy. What is the PCB TOP Side temperature and the peak temperature for Lead Free Wave Sn

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
