Dave, We are using Kester Easy Profile 256 No clean Sn62Pb36Ag02. The oven itself is a Dima SMRO-0252 which is a short oven, it has 13" of preheat, 13.5" of soak, 6.25" of reflow, and 10" of cooling on the way out of the oven. We are soldering multi

Sn62Pb36Ag2 has a higher liquidus point of 189C as compared to Sn63Pb37 at 183C. You may need to slightly adjust your oven profiles to use it compared to SnPb. We have had good solder-ability and reliability with it in our IPC Class II products. A

Morning Mike, We use Pb63/Sn37, Alpha Metal alloy. Solder pot is at 250 C. The profile of board after Preheat about 100 C, Lambda Wave about 220C (use both Lambda and Chip wave), DWell time 2.1s ~ 3s. Conveyor speed 1.5 in/min. We run by bare board a

I have the situation where we may need to use a variety of reflow temperatures. It seems that the design engineers want us to try a variety of "unspecified" pastes on the products. For example, the first PCB would be assembled using a higher temperat

Anyone, We are an electronic assembly contractor and one of our customer requires a 100% solder coverage on pads for their products. We are using flex pcb and we mount only one component (LED for backlight application). The solder paste we are u

GR@ICS, can you be more specific about your up in the Ersa machine please? Nozzle size, pump rate (%), and is your machine equipped with monitors on the solder pots? We have the same machine it sounds like, however we run Pb-Free in both pots. I

| | We process both tin/lead plated boards and gold plated boards in our surface mount group. I have used Sn62/Pb36/Ag2 solder paste on all gold plated boards to help prevent gold scavaging. To reduce the amount of different solder pastes we have t

Hello Dave, Mechanically the conection between the component pad and PCB pad is good (the solder joint is very strong). The problem is associated with poor contact after the use by the customer (vibration, temperature, etc). You can see the pictures

I'm looking for a PbF solder paste with similar characteristic as the 63/37Pb alloy. What alloy composition would you recommend?
