Dear Everyone, I'm having problem. the Switch component drop after reflow. First, this component placed on top side and through Reflow. Next, the Bottom side is placed component and through reflow. After that, the switch drop and have a gap. We are u

Hi, We have a new product coming soon that has a fair number of PTH sockets and headers. I was thinking that it would be good to use intrusive reflow on some of them to even up cycle times between SMT and hand insertion, however, when i called t

I am referring to reflowing twice. Fist time I reflow the up side, turn the PCB and reflow the bottom side. | By double reflow are you referring to double sided reflow? Or are you referring to reflowing twice? | | | | I would like to have informat

I have a customer that is wanting to use a low-temp solder paste such as SnBi for a lead free circuit, however they are specifying PET for the flex circuit. I have always used polyimide for SMT reflow due to the temperature limitations of polyester.

Has anyone had any experience or data using vibration during the reflow process. We introduced a vibration device attached to the fixed rail on a Vitronics reflow oven. The reason was to prevent skewing on large PLCC devices. The process worked very

I did some investigating and it seemed that getting a reflow oven with an inert atmosphere could be the answer to the inconsistant wetting issues that we are having with a leadfree DFN-10 on one of our products. Here's my question(s). It seems that

I have a strange problem with 1208 resistors flipping off placed position. I have the same reflow settings that I have used for years with the same solder paste. PAste is only a few months old and it was used just 1 week ago without problems. Some re

Anyone use glass filled nylon connectors utilising the intrusive reflow techique (pin in paste). We are having probe with them becoming brittle after reflow- apparently due to moisture. We are also seeing bubbling on outside plastic.Peak oven temp 22

Marc, There are many types of nylon used in the connector industry and some are designed to be used in high temperature (225-250C) oven reflow applications. These high temp nylons are usually types 4/6 and 6T. It sounds like you are either using a

hi, encounter few cases PCB was delam after reflow, and the supplier was refuse that this is a PCB manufacturing defect as the fallout is low within one lot. the cost for this scrap is high after PCBA level, my query here are 1) is there any way
