Laser cut SMT Stencils for PCB assembling units.

Prototyping SMT Stencils for µBGA and similar smaller size components requires Fine Line Stencil technology. The whole affair of developing Prototype SMT Stencils is an expensive and meticulous job but nevertheless in big demand by mass PCB assemblers.

A PCB (printed circuit board) would not invite a second glance from us but if we only come to know behind the various technologies involved in making them, we would probably say a silent thanks to the inventors of Gerber file format and software developers of CAD and CAM.

In addition, another recent technological advancement used in creating SMT Stencil is laser. To produce prototype Stencil for soldering minute semi conductors and chips, laser is employed to cut the base stencil material for surface mounting.

I gathered this much information for the benefit of a young electronics engineer who wishes to start his PCB assembling unit in a small scale.

What goes around comes around-a proof.


Fleming was a poor Scottish farmer. One day, while trying to make a living for his family, he heard a cry for help coming from a nearby bog. He dropped his tools and ran to the bog.

There, mired to his waist in black muck, was a terrified boy, screaming and struggling to free himself. Farmer Fleming saved the lad from what could have been a slow and terrifying death.

The next day, a fancy carriage pulled up to the Scotsman's sparse surroundings. An elegantly dressed nobleman stepped out and introduced himself as the father of the boy Farmer Fleming had saved.

"I want to repay you," said the nobleman. "You saved my son’s life."

"No, I can't accept payment for what I did," the Scottish farmer replied waving off the offer. At that moment, the farmer's own son came to the door of the family hovel.

"Is that your son?" the nobleman asked.

"Yes," the farmer replied proudly.

"I'll make you a deal. Let me provide him with the level of education my own son will enjoy if the lad is anything like his father, he'll no doubt grow to be a man we both will be proud of." And that he did.

Farmer Fleming's son attended the very best schools and in time, graduated from St. Mary's Hospital Medical School in London, and went on to become known throughout the world as the noted Sir Alexander Fleming, the discoverer of Penicillin.

Years afterward, the same nobleman's son who was saved from the bog was stricken with pneumonia.

What saved his life this time? Penicillin.

The name of the nobleman? Lord Randolph Churchill ... His son’s name?

Sir Winston Churchill.

Someone once said: What goes around comes around.

Moral of the story: Work like you don't need the money.

How to pray to get what you want?

A voyaging ship was wrecked during a storm at sea and only two of the men on it were able to swim to a small, desert like island. The two survivors, not knowing what else to do, agree that they had no other recourse but to pray to God. However, to find out whose prayer was more powerful, they agreed to divide the territory between them and stay on opposite sides of the island.

The first thing they prayed for was food. The next morning, the first man saw a fruit-bearing tree on his side of the land and he was able to eat it's fruit. The other man's parcel of land remained barren!

After a week, the first man was lonely and he decided to pray for a wife. The next day, there was a woman who swam to his side of the land. On the other side of the island, again there was nothing!

Soon the first man prayed for a house, clothes, more food. The next day, like magic, all of these were given to him. However, the second man still had nothing!

Finally, the first man prayed for a ship, so that he and his wife could leave the island. In the morning, he found a ship docked at his side of the island. The first man boarded the ship with his wife and decided to leave the second man on the island. He considered the other man unworthy to receive God's blessings, since none of his prayers had been answered.

As the ship was about to leave, the first man heard a voice from heaven booming, "Why are you leaving your companion on the island?"

"My blessings are mine alone, since I was the one who prayed for them," the first man answered. "His prayers were all unanswered and so he does not deserve anything."

"You are mistaken!" the voice rebuked him. "He had only one prayer, which I answered. If not for that, you would not have received any of my blessings."

"Tell me, O God," the first man asked the voice, "What did he pray for that I should owe him anything?"

"He prayed that all your prayers be answered."

For all we know, our blessings are not the fruits of our prayers alone, but those of another praying for us.

This is too good not to share...

My prayer for you today is that all your prayers are answered. Be blessed.

"What you do for others is more important than what you do for yourself"
