Hi, I have seen the oscillation frequency change in higher humidity environments. Was doing some data acquisition in a high humitity environment in 1990 using some off the shelf loggers. The data that was collected was incorrect. Found out the cr

We are installing via reflow soldering a crystal that has 2 pads, 1 each end. They are flat pads on the bottom of the part with a small area of the pad looping around and up the side of the crystal on the end. Inspection of the cyrstal under a 40X

Sean, We suggest having the PCB tested for ionic cleanliness. It is conceivable that though the visible flux residue has been cleaned, there is still invisible, yet ionically significant residue in the area of the board/part. We also suggest ensur

I have been using this series with AIM SnPb no-clean paste without problems.

Sounds like you're not getting the solder connection hot enough. Talk about: * Temperature of the solder on the connection * Solder alloy * Board solderability protection * Component solderability protection

Hi all, Is anyone used to encounter PTH(plated through hole) crystal component(Not SMT component) become malfunction when the environment humidity is more than 90%? It is happening here...It is very weird that crystal become OK when humidity is bac

Upside down placement of a crystal oscillator is acceptable or not ?? As per IPC 8.3.2.9.2 Rectangular or Square End Chip Components – 1, 3 or 5 Side Terminations.I am not sure whether is applicable for crystal oscillator or not . Your answer wo

What kind of oscillator are you placing (Manufacturer part #)? I do not believe that oscillators fall under the "chip component" category. Even if they did, most all SMT oscillators that I have come into contact with have 1 sided terminations on the

We wave [primary side] and reflow crystals for oscillators without fear. We hand solder liquid crystal displays. Consider checking with the crystal fabricator and using their guidelines.
