Wave Solder Pallet Compatibility 2440×1220 Suitable for High Temperature

Wave Solder Pallet Compatibility 2440×1220 Suitable for High Temperature

Specification:

Feature

1. Used materials imported synthetic stone materials, quality imported bakelite, glass fiber, alloy
2. Reflow soldering printed circuit board tooling
3. Decrease deformation of the substrate caused by the tin stove and electrostatic breakdown
4. Applicable substrate shape
5. Loading multiple PCB production line, saving manpower and after welding, improve productivity

PTH Components Located Perpendicular to direction through wave.

A larger separation is required due to the solder having to flow "under"
component pockets.

Working your way around the underside of the PCB, identify which components
are parallel and perpendicular to the wave and assess the solderability of each
PTH connector by comparing the actual separation against the graph right.

Ideally you want to be above the line in all cases.

PCB Design Implications - for Board Designers - or respin

We are often called upon by our customers to help with identifying design respin opportunities.

We will identify problem areas within a board and suggest appropriate movements of components. (Ideally before the PCB is fabricated)

However for board designers reading this, can you remember another four "rules" (to compete with the hundred other rules you have to have floating
around in your head).

Keep large (height) SMT components away from PTH areas.
Leave the leading and trailing areas around PTH components as clear as possible.
DON'T put any SMT components within 3mm (0.12") of any PTH components.
DON'T put all PTH components in line along one edge of a board - leave some space to allow us to support the masking in the centre of the board.

We recommend to use Reflow Pallets of Durostone Material, for your different PCB shapes, thin PCB material use to avoid warpages on your assembled board. You will be able to work effective with every kind of shapes and material thicknesses.

The following are the general data files required for fixture development. Products are processed differently. Supplying us with all of this data will ensure that we have what is needed for your application.

Top & Bottom Side Silkscreen
Top & Bottom Side Paste
Top & Bottom Side Mask
Fabrication Drawing
Drill Fab Layer

Other Requirements:
Height of components on the solder side of the PCB
Height of components requiring hold downs
Identify any components which overhang the board and whether they seat flush to the top of the PCB or receed to a certain depth

FAQ

(1) Discount price yes&no ?

It is depending on the volume. The larger the volume is, the more discount you can

enjoy.

(2) Why your price is a bit higher than other Chinese suppliers?

To meet the requirement of different customers and areas, our factory manufactures

various kinds of quality for each item at a wide range of price. We can offer the

products of different quality levels depending on customer’s target price and quality

requirement.

(3) If I can get a sample ?

For existing samples (sizes not larger than 300*300mm) can be sent free of charge

but you just need to bear shipping charge, or you can provide your DHL, FEDEX,

EMS, UPS courier account number to us.

For bigger sizes, or customized samples, it depends on negotiation.

(4) If you can guarantee the quality of mass production is same

as the sample sent to me before?

Quality is our culture, is our life. We believe our products will give you a surprise.

Our warehouse staff will leave another same sample in our workhouse, and marked

your company name on it, which our production will be based on.

(5) How can you deal with quality issues after receiving the goods?

1) First you take photos of unqualified goods and then our sales staff will send

them to Manufacturing Department to verify.

2) If the problem is confirmed, our sales will explain the root cause and take

corrective actions in coming orders.

3) Finally, we will negotiate with you to make some compensation.
