Through-hole PCB Assembly

2017-10-14

Shenzhen Grande Electronic is fully capable of providing prototype and small quantity, through-hole PCB assembly services at the highest quality level possible in a cost effective manner.

Printed Circuit Board (PCB) First Article Assembly

2017-10-10

Shenzhen Grande Electronic offers printed circuit board (PCB) first article assembly at the most reasonable prices than any other electronic contract manufacturers.

PCB Solder resist

2017-09-28

Solder resist has become an integral part of Printed Circuit Board (PCB) technology today.

Which Soldering Defects are Related to the Incorrect Setup of the Reflow Profile

2017-09-26

As shown in the figure below, there are four different zones in a typical refow profile – pre-heat, pre-heat and soak, reflow, and cooling zone.

Why does Shenzhen Grande Use a 10 Zone Force air convection reflow oven?

2017-09-25

Shenzhen Grande uses the JTR-1000 ten zone force air convection reflow soldering system because it delivers more accurate thermal control and has power efficient technology.

When do you set different temperatures for the heating elements?

2017-09-22

The SMT process engineer should review the specific board requirements to determine the correct settings.

SMT: The Application of the Pin-in-Paste Reflow Process

2017-09-21

The Pin-in-Paste (PIP) reflow process, also called through-hole (TH) reflow or pin-in-hole (PIH) reflow technology, has become more popular because it eliminates time-consuming processes

SMT: Pin-in-Paste Reflow Calculations and Special Cases

2017-09-20

The major concern of the pin-in-paste SMT reflow process is the quality of the solder joint. It must meet IPC610 standard.

SMT：Reflow oven zone temperature set up and thermal profile

2017-09-14

The process of hot air reflow soldering is essentially a heat transfer process. Before starting to “cook” the target board, the reflow oven zone temperature needs to be set up.

The Sizes and Usable Areas of PCB Panels

2017-09-12

The most cost-effective PCB panels have a larger processing area. That’s why the most desirable PCB panels are 12in by 18in, 16in by 18 in and 18in by 24 in.
