Component manufacturers subject their lots to thermal / reflow testing per IPC /JEDEC STD-020. This involves running the parts through an oven 3X with a peak above 260C. I am not certain if passives go through the same test (theoretically they shou

yes, you should look to see on that particular feeders Z axis setting. When the tip goes down to the part it may be traveling down little too much. Just make sure you check which way is your - and + increments going and do not exceed more than 30 or

First, don't exceed the maximum temperature of the battery, say 85*C [I don't know your specifics] Second, don't short the terminals of the battery. Third, the best way to wave solder a battery is: * Insert an insulating tab between the battery an

Basically the contract comes first, then the design drawings then IPC. if your costumer is asking you to bend the PCB then it becomes apart of the design drawings. as for looking for a cover, get it in writing that that's what they want you to do. I

The recommended wash concentration for stencil cleaning with VIGON SC200 is 25% and this should be confirmed using the ZESTRON BA-20 bath analysis kit. Additional cleaning recommendations are: Wash temperature should be approximately 25 degrees C. /

We are currently experiencing with our SMD Solder Reflow Equipment on Shooting-Up Zones (Zones 3,4,5,7 & even Cooling Zone). PV exceeds about 5-10 degrees with the SP. (ex: SP=140deg, actual PV = 145deg & higher). Our equipment undergo a monthly prev

The z-rod bellows on head 2 and head 3 are slightly bent. The machine will show you this error if the runout is over 6.5 mils. This is usually caused by too much z when picking parts out of a vib or tray feeder. The machine will probably run. I ha

Hi Thomas, Yes, we are pretty good at feeder maintenance, we gang pick on our Yamaha/Assembleon kit with no issues. On one of our older machines (YV112-3/Sapphire) we pick 12 LEDs at once per side of the machine. On a couple of jobs we exceed the ma
