Hi: Many 75ALS573DW parts we reveived lately from one of our vender have some problem with its pin 2, an output pin of the tranciever ( probably resulting from EOS damage). Its impedance verse GND should be normally 3M ohm up. The parts we have measu

Hi Adam, if your product needs the full width of your wave you won�t have any chance to adjust an angle. For smaller PCB�s you might consider having your carriers made in two pieces. One outer piece to match your transportionsystem and one inner cir

We regularly add entries to the industry directory for companies and societies and associations that we think would be of interest to the SMTnet community. We invite a contact there to come and "claim" the mini-page. In the instance or instances yo

Mikeal�s approach is one of the more cautious ones. IPC/JEDEC J-STD-033 clause 8.6 talks about 200�C body-temperature not to be exceeded and how it�s best measured. If you go for that method and you made sure that in your wavesoldering (that�s what

There are a large number of variables that determine how many tabs are needed. The biggest ones I can think of, off the top of my head are. Board thickness .031 needs more than .093 Process and equipment used in assembly some processes and equipment

Our company is in the process of doing a modification to a board that requires running 3 wires. We would like to use tape dots over liquid adhesive because of the ease of removal and no mess. Can someone give me some manufactures of the tape dots? I

I have done both. If you have a line that runs both sides in none pass, running the adhesive side first allows you to have one less machine or station for board flipping. If you have to move the board from one line to another, or back to the front

I have two questions 1. How do I control the skewing of FETs/power regulators ? ( the one's with the big rectangular pad and two smaller one's for the leads).If I go 1:1 with the apertures I seem to get solder balling and when I tryed to minimise th

1. Verify all the part had load to machine. Get ready for the profile. 2. Run the board with double side tape. Is better to run one board for each machine. 3. Verify all the placement ( missing, misalgnment,etc )and check the value using meter for a
