Hello, I'm printing adhesive in one of my products using 0603 components, and I'm facing some issues when PCB goes through Wave Solder, I'm checking the right amount of adhesive & termal profile, but missing components still being my headache, I know

D8->D7) and D18 (D18->D19->D18). Well... it looks like D18 had an issue so it went to D19 but when it finished the D19 reel it went to D7!. I endeed up with D7 parts in place of D18. These are both 0805 resistors. Has anyone seen this ? Did I mis

We are working on placing an RF shield. Sometimes we have been dispensing paste (if the board is already populated), othertimes we have been printing the paste pattern (unpopulated board). Now we have a case where the customer is insisting on a pre

If you are using the upward camera then you probably have to put in a placement offset for each head. This only effects upward camera placements...not quadalign. This is located in: 1. machine-calibration-camera lens 2. Choose upward camera2 under "

Hegemon, Thank you for the acknowledgment. Jacki, There are 3 rosin flux categories: R – Pure rosin (no cleaning required) RMA – Rosin mildly activated (can be used without cleaning in non critical applications) RA – Rosin highly activated (due t

We want to handle the materials such as PCB & MSD components as per IPC 1601 & J-STD-033. As such, we need a baking oven to perform this and to monitor (temperature – we have to maintain up to 200’C & humidity – below 5%)the control environment & ma

A baking oven over 100 C will be at zero humidity. Do you really need to store pcbs/devices at 200 C...this will surely harm some products ? IPC 33B01 allows storage of MSDs in a dry cabinet at less then 5%.....these can operate at room temp or 40 /

In an oven over 100 C any moisture will escape through vents. There will not be huge volumes of moisture in the oven when you are baking components so it should easily escape through vents / holes in the system leaving you with a humidity of near zer

Reading some spec sheets and am seeing profiles for reflow and TTW soldering. A Google search tells me that TTW means "through the wave". Am seeing this acronym on LEDs mostly. I have never seen this acronym before. Why not just wave or reflow so
